Noise and airs are often generally subtle enough in their fluctuations to become imperceptible, defining the background of an environment due their persistence. By virtue of their existence as part of the background of the day to day experience of an environment, they constitute that which a sound or smell must set itself apart from in becoming perceptible or moving to the fore. Both often fall beneath the thresholds of conscious perception, temporarily slipping into imperceptibility, while at the same time defining these thresholds.
Below are some experiments combining background noise and data derived from the quantaties of diverse airs populating the background of our respiratory and olfactory experience.

Earlier today I popped out to deposit a canary in Ford Park to gather more data. As I felt I needed the exercise I took a walk over hoad hill on my way to pick up some more wool from Loopy’s in Ulverston. Coming down off the hill into the town I immediately became aware of a faint but foul stench, reminding me of both Painthorpe pig farm and the smell of burning hair during boring science lessons at school. This smell grew stronger as I got further towards the town centre. I spent a little time trying to locate the source of the smell but most of the clouds emitted from the buildings in town were pleasantly fragrant in comparison. The situation continued to get worse and a thick mist descended upon Ulverston. I returned quickly to Lanternhouse to get a mobile canary in order to investigate any possible correlations between what I was smelling and the overall quality of the air. I followed the cloud from Neville Street to the edge of Ulverston along Stockbridge lane, at which point the smell began to disappear, so I headed back into town to gather what data I could.
Despite the canary not being calibrated and therefore not being able to give precise readings on what amounts of which chemicals are present in the air, we can contrast the results gathered using the same equipment on different days. Ruskin characterised the plague-clouds descending upon Coniston according to their erratic movement. While I can’t comment on the visual movements of the cloud surrounding Ulverston this evening, the reading I was getting while seeking out its thresholds were certainly erratic in contrast to that which I’ve become accustomed to seeing while walking around the area. The first two images above show a plot of air quality against location gathered earlier this evening. The faint green line shows the route taken through town and the size of the circles indicates fluctuations in air quality. The third image is a plot of a similar walk taken a couple of days ago, on what can be considered a fairly normal day in Ulverston with only very minor fluctuations in air quality throughout the town. There was something in the air tonight, and it wasn’t very nice.
An alternative plot of this evening’s data:
Some notes on the broader concerns of the invisible cartographies project:
There are two sides to the invisible dynamics of the landscape revealed by this project. The first presents these dynamisms as components or qualities of the landscape as an objective reality, as fluctuations that are part of the landscape itself and not simply perceived fluctuations or subjective variations determined as such according to given thresholds of perception. The second is not wholly separate but certainly different in that it is focussed upon these same fluctuations as they occur within the proximity of a human body. This latter point refers to the data gathered by the mobile or bluetooth canaries which log fluctuations in localised atmospherics against latitude and longitude, fluctuations occurring around the human carrying the device and therefore charting an atmosphere to which the carrier or walker contributes through their breathing or other gaseous expulsions.
Proxemics
The above image is an attempt to show the second of the two orientations mentioned above. The faint green line shows a walk around Ulverston, the centre of each circle indicates a point on the walk at which a sample of the air was taken. The varying diameter of the circles shows fluctuations in air quality. This seems like a particularly suitable way of expressing a kind of gaseous proxemics visually. Proxemics is a term taken from the work of Edward T. Hall. Proxemics can be thought of as the study of personal space, but more precisely it’s socio-cultural or broadly contextual flexibility. A proxemic boundary can be considered broken when another person stands too close. Anyone with a sibling has surely unknowingly experimented with proxemics on long car journeys as a family: one child puts a hand close to the body of the other while claiming that they’re “not doing anything” as their is no physical contact being made. The other child calls out to the parent that their brother/sister is “in my space”, the limit of this space being perceived to be highly ambiguous and often getting little support from the parents. The proximity of the hand to the body of the brother or sister is, however, certain to annoy due to proxemic or personal space being transgressed. While from the outside, or the front of the car the boundaries of the spaces between kids in the back are hard to determine, the kids know precisely where they lie and how to manipulate them. This is of course a really simple example of the complex components and contextual determinants of personal space, which Hall describes in more detail (see The Hidden Dimension). Of particular interest to my own work is Hall’s discussion of auditory and olfactory proxemics, or the contribution of sound and smell to the determination of personal space. The work I’m doing as part of this residency can’t really be considered proxemic research as proxemics are always concerned with the thresholds of interpersonal space, and much of the work I’m doing involves walking alone or in small groups with the focus being placed upon the material composition of an invisible space rather than the interpersonally determined thresholds of personal space, invisible or otherwise. The reason for bringing this up here is that the work being done in mapping atmospheres that circle the body can perhaps be thought of as impersonal proxemics, insofar as it is concerned with the particular elements that contribute to a personal atmosphere that circles individuals and constitutes an ambiguous boundary. While this is less about interpersonal space, this is due to the fact that it is more concerned with how impersonal and inhuman elements nonetheless contribute to what we think of the personal or the space of the self.
Diffuse Bodies
This project is orientated around the diffuse interactions of bodies, human bodies, bodies of air, micro and macroscopic bodies; it busies itself charting the spatio-temporal contingencies of the confused and corpuscular space of which the self is composed. The human as one such body appears in this schema as being composed of―as well as constantly decomposing into―a corpuscular space or atmosphere that both surrounds and permeates individual, proxemic territories. This project approaches the self in terms of a corpuscular space that determines its proxemic territory, the self and not just the body, as this would be both too simple and reductive as the body is clearly observed as being composed of a number of potentially autonomous units. Perhaps there is a tendency to think of the self as a more unitary and unified mode of existence, such as where we write “I” but could just as easily read this symbol numerically as 1. The self thought as diffuse and dependent upon a corpuscular space is thought in a manner more thoroughly confused with a wider environment or atmosphere upon which it depends and with which it is enmeshed. In this model the self is thought as the composition of every element comprising the confusion of body, soul and ecological atmosphere.
The Particular Importance of the Invisible and Corpuscular
Foregrounding the invisible movements, interactions and constitutive contingencies of that which is apparently solid and stable serves to alter and embed a critical function within those thresholds of perception that are allowed to contribute to ontological determination where we hold too strongly to empiricism. We currently face catastrophe, and a factor contributing to the denial of our own implication within this calamitous future is the common ease with which stability and solidity are taken as the chief characteristics of reality, as it is perceived by the eye, ear, or senses in general. We cannot rely upon that which gives itself to perception, upon that which is easily and readily perceived according to inherent sensory capacities, and so we must forcefully bring to the fore elements and qualities of that which resists, ‘withdraws’, or rather exceeds the possibility of perception according to the thresholds of perception as they are simply given. The example that always springs to mind here is of the enormous problem of plastic in the oceans. I once heard a radio programme where two Women out doing research in the pacific described beautifully clear water on a lovely sunny day. They then went on to talk about how the water for miles around was saturated with microscopic particles of plastic that were clogging the up the bodies of marine life. The visible plastic was less of a problem, but would eventually be broken apart and spread itself over thousands of miles into the guts of thousands of fish, mammals, birds and so on. Where we remain focussed upon an understanding of the environment that relies upon that which is empirically justifiable such problems pass us by. In a similar way we might think of Ruskin’s plague-clouds and ‘calamitous winds’ which can be thought as close relatives of smog. While the smoke and smog of the industrial revolution may have cleared and been sandblasted from the walls of our cities, we now face an invisible yet nonetheless substantive threat in the form of pollution that persists, in part at least, due to its imperceptibility. On the subject of “plague-winds”, “smoke-cloud” and “dense manufacturing mist” Ruskin commented on “the uselessness of observation by instruments, or machines, instead of eyes”. It is this sufficiency of the given thresholds of perception that we must continually move beyond in order to take account of the substantive operations of the invisible and imperceptible, embedding them within our image of reality.

Ideas on how to integrate the location data with the shifts in airs when creating patterns are warmly received.
In carrying out research into the history of air while working on this residency, Ruskin came up a number of times, which is not surprising giving the location of the residency. I know very little of Ruskin, but have found his meteorological speculations fascinating since digging out his two lectures on The Storm Cloud of The Nineteenth Century. Ruskin made many studies of clouds, some of which I had the pleasure of seeing last Friday at Brantwood. Rather than his aesthetics, it is on the concepts presented in his lectures on clouds, presented to the London Institution in 1884, that I’d like to focus on now. All the quotes below are taken from the transcript of the lectures available here: http://www.gutenberg.org/ebooks/20204 . What follows is a few quick notes on what I consider the highlights of these lectures. It is these lectures that I’m particularly interested in as they contain a mixture of careful description with physical and mystical speculation on the nature of diverse clouds. Perhaps unsurprisingly, clouds are defined as such by Ruskin according to their visibility, yet this distinction is not made without ambiguity as Ruskin will speak of airborne bodies composed of “an invisible, yet quite substantial, vapour; but not, according to our definition, a cloud, for a cloud is vapour visible.” While not a cloud, these invisible vapourous bodies nonetheless remain substantial, affective objects. Ruskin goes someway to beginning a taxonomy of clouds based around floating “sky clouds” and falling “earth clouds”, but it is the bodies of air that are not quite clouds that I find particularly interesting, the mists that Ruskin identifies as existing in-between sky and earth clouds. It is the status of being in-between that is particularly interesting as it is that which does not quite satisfy Ruskin’s taxonomic criteria for cloud status that pertains to the invisible and to the diffuse bodies of a subtle and subliminal influence. This in-between status alludes to a body of air in transformation, between states, in flux; it is this being in-between or interstitial existence that is in part behind Deleuze and Guattari’s mention of fog and mist where they relate both theses states of the air to what they call a haecceity, a being that is in the process of becoming something else, always in a state of change, ephemeral and contingent: ‘ a haecceity is inseparable from the fog and mist that depend on a molecular zone, a corpuscular space’, (A Thousand Plateaus, 301).
Beyond Ruskin’s general work on clouds, it is the concern he expressed for a dark and menacing wind or cloud particular to the 19th century that is really interesting: “This wind is the plague-wind of the eighth decade of years in the nineteenth century; a period which will assuredly be recognized in future meteorological history as one of phenomena hitherto unrecorded in the courses of nature, and characterized pre-eminently by the almost ceaseless action of this calamitous wind.” This calamitous wind is most easily characterised as the product of rapid industrialisation and signals Ruskin’s environmental concerns, but what is of particular interest is that the action of the plague-wind or cloud cannot be neatly restrained to the problem of pollution, insofar as Ruskin bears what we would now refer to as a broadly ecological understanding of its contingencies, interconnections and extensions, with cloud formations occupying the position of a medium between industry, politics morality and subjectivity. The extent of Ruskin’s implication of the plague-cloud within an ecological field comprising the political, spiritual and environmental can be seen in the second of his lectures on the subject where he describes “the clouds and darkness of a furious storm, issuing from the mouths of fiends—uprooting the trees, and throwing down the rocks, above the broken tables of the Law, of which the fragments lie in the foreground.” Here the nephological is understood to seep not only into organic bodies but to infiltrate the Law, which due to its capitalisation should be read as referring to the domain of morals and ethics in general, to an order of social power and control.
Ruskin’s plague cloud “looks partly as if it were made of poisonous smoke; very possibly it may be: there are at least two hundred furnace chimneys in a square of two miles on every side of me. But mere smoke would not blow to and fro in that wild way. It looks more to me as if it were made of dead men’s souls—such of them as are not gone yet where they have to go, and may be flitting hither and thither, doubting, themselves, of the fittest place for them.” Here the plague-cloud is not limited to being thought as solely produced by furnaces and composed of the diffuse elements of burnt offerings to industrial progress (the “sulphurous chimney-pot vomit of blackguardly cloud”), but as being confused with the soul and the flight of the dead, echoing conceptions of the air as the medium of the spirits that has persisted for millennia. The broadly ecological (by which I mean an understanding of the interconnectedness of all things rather than the strictly ‘natural’) implication of the nephological, of clouds, mists and winds, within a distinctly moral and spiritual order can be found in Ruskin’s conclusion to the first lecture:
“Blanched Sun,—blighted grass,—blinded man.—If, in conclusion, you ask me for any conceivable cause or meaning of these things—I can tell you none, according to your modern beliefs; but I can tell you what meaning it would have borne to the men of old time. Remember, for the last twenty years, England, and all foreign nations, either tempting her, or following her, have blasphemed the name of God deliberately and openly; and have done iniquity by proclamation, every man doing as much injustice to his brother as it is in his power to do. Of states in such moral gloom every seer of old predicted the physical gloom, saying, “The light shall be darkened in the heavens thereof, and the stars shall withdraw their shining.” All Greek, all Christian, all Jewish prophecy insists on the same truth through a thousand myths; but of all the chief, to former thought, was the fable of the Jewish warrior and prophet, for whom the sun hasted not to go down, with which I leave you to compare at leisure the physical result of your own wars and prophecies, as declared by your own elect journal not fourteen days ago,—that the Empire of England, on which formerly the sun never set, has become one on which he never rises.”
The plague-cloud here constitutes a grim and filthy prophecy, being enfolded within a moral, spiritual and political order. That these clouds should have been thought by Ruskin to have moral and spiritual implications is not entirely surprising when taken in the context of certain aspects of scientific and philosophical thought prevalent around the time he presented these lectures. During the 1870′s, there are accounts of not only the physical impacts of diverse atmospheres such as tropical climates upon immigrant and primarily colonial populations, but also the moral impact of the climate upon its ill-prepared, ill-tempered, or ill-weathered European subjects who sought to exploit the resources of far-off lands ( a nice introduction to these ideas can be heard here http://www.bbc.co.uk/programmes/b00wfhgg ). While there is a highly dangerous element to this kind of thinking on climates and atmospheres, a danger that persists where environmental determinism is allowed to remain unilateral, according to which people are simply a product of their environment and the subjects of climate, where the influence of atmospheres and environments is taken amidst a broader approach to atmospheric influence and environmental interactions it helps account for the nuances of ecological relations, including (as in Ruskin’s work) the natural, synthetic, political and spiritual.
There are a few fragments within the two lectures that I find particularly interesting from the point of view of artistic practice and spatial productions, namely the moments where Ruskin considers the composition of clouds that are not normally considered natural or strictly meteorological. Considering the malignant qualities of plague-clouds, Ruskin briefly wonders whether “perhaps, with forethought, and fine laboratory science, one might make it of something else”. Here I’m inclined to speculate on Ruskin’s spirit of invention, imagining it turned towards the production of clouds as an artform or architecture of the air, and imagine Ruskin dabbling in the production of clouds of a more agreeable composition, releasing them from a laboratory that was never built onto the side of Brantwood. We can find a further fragment of a larval nephological synthesis in Ruskin’s question: “What—it would be useful to know, is the actual bulk of an atom of orange perfume?—what of one of vaporized tobacco, or gunpowder?—and where do these artificial vapors fall back in beneficent rain? or through what areas of atmosphere exist, as invisible, though perhaps not innocuous, cloud?” In these questions we find Ruskin considering atmospheric production by means of perfume, explosions and smoking, and an altogether more experimental mode of thinking on the subject of atmospherics and cloud production.
Hopefully by the end of this residency I can draw up a reading list to enable me to take these speculations further.
These final images were taken during an earlier trip to Coniston to gather samples in Ruskin’s garden:
A static canary was left in Ford Park to see what invisible and diffuse bodies were passing through it over a 24 hour period (see invisible.folly.co.uk/ford-park/). After 24 hours in the park, here’s the data it gathered on general fluctuations in airquality:
Mostly there are only minor fluctuations, apart from the huge ravine that occurs later in the plot. As the static canary is only a simple device it doesn’t log the time that values are written to its SD card. To figure out the time at which this dip appeared I wrote a small python script:
file = open("~/Documents/FLI/Static_Plots/Ford_Park_Hedge/LOG00129.txt") i=0 hour = 16 day = 1 for line in file: if line == '\n': continue else: i+=1 if i%60 == 0: hour += 1 if hour%24 == 0: day +=1 print str(day)+"-"+str(hour%24)+"-"+str(i%60)+"\t"+str(line),
hour = 16 because I turned the device on at roughly 16:00 on Tuesday this week. The canary records one value every minute so the rest of the script uses this fact to figure out the approximate time of each plot:
(day-hour-minute value)
2-10-57 414 2-10-58 414 2-10-59 414 2-11-0 413 2-11-1 413 2-11-2 413 2-11-3 412 2-11-4 412 2-11-5 411 2-11-6 410 2-11-7 410 2-11-8 409 2-11-9 408
the output from this shows the dip happening around 11am on Wednesday 1st December. The cause is presently unknown.
There are lots of things I really like about the Lanternhouse, it’s a beautiful building full of great people in a great town. Tonight my appreciation of this place went up another couple of notches, when I found this fantastic collection of books stacked up on a table in what is to become the new library:
Raymond Williams : The Long Revolution
Urban Art in the New Century
E. P. Thompson : The Making of the English Working Class
Fox and Kemp : Interactive Architecture
Geoff Manaugh : The BLDBLOG Book
http://www.popsci.com/science/article/2010-10/titan-smog-may-hold-ingredients-life-new-study-says
I find the title of this article interesting as smog is normally considered amongst the demonic airs, but here it receives a certain vital association with the potential origin of life.
After a spot of litter collecting with the volunteers at Ford Park this morning, we decided on a couple of good locations for the static canaries (the name given to the sniffers by Lanternhouse’s Programme Director Claire Benbow). This particular version of the device is designed to be left for long periods in one place, rather than carried during walks, so simply records fluctuations in air quality without the gps data. Recording started at approximately 16:00 today (Tuesday 30th November); I’ll return to collect the canary on Thursday morning to see what data has been gathered. As the weather has become a little more harsh in recent days, a hi-tech anti-snow device was required:
For getting quick results from the data gathered on walks over the hills of Ulverston I’ve been using gnuplot for some basic visualisations. Once the plots are generated they can be quickly and easily arranged for cross reference using imagemagick. Commands below.
Gnuplot commands for the above:

This afternoon was spent working on further power saving measures and then another test run up the hoad and down through Ulverston town centre. After getting back to Lanternhouse and thawing my icy fists, I thought it might be nice to try out some methods of combining the elevation data with the data gathered from the various gas sensors being used on these walks. The three images above are i) latitude, longitude, elevation ii) latitude, longitude, ozone intensity iii) latitude, longitude, elevation - ozone intensity.
Above is the terrain data from today’s test walk, just latitude, longitude and elevation in gnuplot’s beautiful default colour scheme. The sniffer has been fixed and bottled up.
It’s interesting that where yesterdays walk plotted general air quality against landscape and came up with something not too disimilar from that which is visible (see: http://invisible.folly.co.uk/hoad-plots/) plotting ozone concentrations (z) against latitude and longitude (x,y) produces a dramatically different image of the landscape. In the above image the terrain data (green) and a plot of latitude, longitude and ozone concentrations (purple) are overlayed to stress this difference. Below are some further maps of the route taken today and images from a few notable locations.
Nearby, someone was building a house.
Slimy and decaying seating, found just beyond the border of Ulverston.
After spending yesterday evening working on a low power version of the sniffers, the sun finally shone on Ulverston today, so I did a quick test run up to the hoad monument which towers above the town. The images above only really show half a plot as I broke the power cable at the top, hopefully tomorrow will be equally as nice a day and I can do some more thorough tests. The data for these images was gathered during the 35 minutes it took to walk from Lanternhouse to the top of Hoad Hill. The first shows the gps coordinates and elevation, the second shows airquality against latitude and longitude, the third shows the sniffer shortly before I broke it, and the fourth shows the route taken.
(Thanks to Martin Howse for the introduction to gnuplot).
There have been a lot of ideas bouncing around since starting this project, a few of them are briefly discussed below and will hopefully be elaborated upon in the near future. These points are mostly based upon the idea of air and how it has been imagined since antiquity.
The desire to work with airs apart from their sonorous renderings in the ear (which describes the state of vibrational matters I normally choose to work with) was driven by an interest in thinking about sound beyond the ear, the nature of sounds not heard. Removed from what is normally thought as their constitutive organ (according to which a movement of the air is only called sound insofar as someone hears it) these inaudible ‘sonorities’, or more simply vibrations, are constituted purely according to that which resists of exceeds the possibility of perception, existing as that which sound is in-itself when there is no one around to hear it. This has taken me to the elements making up these disturbed bodies of air that are named sound upon setting the ear in motion, the minuscule elements that make up the medium through which we most commonly hear. The work I’m undertaking as part of Invisible Cartographies is a set of preliminary experiments in engaging with some of the constituent elements of the airs through which we hear that persist beyond acts of audition, something which has lead towards basic experiments with mapping the components of atmospheric chemistry. The processes described by chemistry draw attention towards a weirdly vitalistic creativity, foregrounding the interactions, interrelations and contingencies of diverse bodies, distinct if a little fuzzy round the edges. The vitality ascribed to airs or gaseous bodies is highlighted by the historian Alain Corbin in his fabulous book The Foul and The Fragrant when he states that, during the late eighteenth century, “to study airs was study the mechanisms of life” (16). Air, while linked to life forces through the vitalistic assertion of an equilibrium between airs and organisms (human, animal, plant … ) is also described by Corbin as “the laboratory of decompositions”, therefore linking it to a process more readily linked to decay and death through the dissolution of bodies into the realm of the imperceptible. Airs have been variously thought to account for both the constitution and dissolution of bodies throughout history, and so this “laboratory of decompositions” attests to a two way motion as the decomposition of one body feeds into the composition of another, establishing a dynamic equilibrium between bodies, whether these be bodies of water, air or animal bodies. Composition is then thought as an ambiguous process enfolding decomposition within its operations, operations that are negative from the perspective of the integrity of the individual undergoing decay, yet positive from the perspective of the infinite interactions that each constituent element or particle enters into within the complex interactions of airborne compositions. Accounting for its contingencies and interactions, a body of air is perhaps best thought of as a particular continuum, being comprised of elementary particles that are shared or passed between individuals in varying degrees of composition and decomposition.
In addition to this weird vitalism that thinks of air as an interactive field of (de)compositions, I’d like to highlight a more fundamental theory of airs that extends back in time around 2500 years, that serves as a link between airs and the constitutive movements of sound, a theory that states that the movements comprising sounds also comprise rocks and earth.
Apart from chemical and particular interactions, there is a productivity to the contractions and rarefactions of the air which allows for its rendering as sound in the ear or as a touch on the skin. The contractions and rarefactions or disturbances of the air productive of what we might call sound objects or audible events were, for Anaximenes (585 - 528 BC), the same disturbances or vibrations that produced stones and earth. Anaximenes’s position on the creative contractions of air is summarised by Theophrastus (371 - 287 BC):
Anaximenes, son of Eurystratus, of Miletus, was an associate of Anaximander who says, like him, that the underlying nature is single and boundless, but not indeterminate as he says, calling it air. It differs in essence in accordance with its rarity or density. When it is thinned it becomes fire, while when it is condensed it becomes wind, then cloud, when still more condensed it becomes water, then earth, then stones. Everything else comes from these. And he too makes motion everlasting, as a result of which change occurs.
I keep this last line in the quote as it is often the movements of diffuse spatialities or airborne bodies that bring about the vitality ascribed to them, as sound or fresh air are often described as bringing a space “to life” by virtue of the movement they instil in what is otherwise perceived to be static, dormant or dead.
The above diagram was drawn up to express units of existence, whether rocks, trees or humans, as contractions of a kind of mist or cloud of particles, a confused material substrate from which identifiable forms emerge. It is in this sense that I find a link between these thoughts on air and the noises I normally work with: air and noise find a certain relation in that both constitute a background to existence, comprising that which slips most easily into imperceptibility through fluctuations in sensory thresholds, while remaining the particular objects of a subliminal influence. The confused bodies of air and noise constitute backgrounds which through their contractions produce the figures appearing to the fore.
Above is Hector Gavin’s mapping of The Disease Mist Overhanging Bethnal Green in the Year 1847, depicting the harmful miasmas which cloaked this particular district of London in a gaseous body of subtle and despicable influence, here depicted in darkness. Further details on Gavin’s project of sanitary reformation and the cartography of disease can be found at the Victorian London site. There is an obvious link between Gavin’s cloud and class that deserves attention regarding the production of a historical and particular territoriality, but this will have to wait for another time. More immediately important for the present project is that this cloud was identified at a time when airborne pollutants were more readily identified within the thresholds of perception, being seen as smog, mists or dust, or detectable as a foul stench. Where the clouds I’m working on mapping as part of this project pose a problem (ecologically, biologically … ) it is one of a more insidious nature insofar as they remain otherwise imperceptible yet nonetheless real.
For the Invisible Cartographies project I’m making two types of devices that gather data on atmospheric chemistry in specific locations: one is a mobile device that relays the information it gathers to a mobile phone (running an Android application I’ve been working on) via bluetooth where it is tagged with GPS data and stored on the phone’s internal SD card for later use, the other is a static device that will be placed in a location and left for extended periods of time.
Yesterday we presented the Invisible Cartographies project to the public for the first time. As part of this presentation Oyunga put together a promotional pack containing a miniature knitting kit and jar of air. It turns out that the jars are the perfect size for the static devices:
This evening I’ll be trying to find a suitable location to hide this in Ulverston, as long as it isn’t stolen I’ll put a quick plot up once I’ve retrieved it.
Tests of the sensor and GPS logging are coming on well. After meeting up with the Lanternhouse knitting group last tuesday I’m keen to pursue wool as both a means of representation of the data gathered during walking, yet more more excited about the social structure of the knitting group as means of discussion and working with the ideas of interest and the data gathered. My knitting is still terrible but slowly getting better with the help of this blog: http://www.bellaceti.com/blog/2009/03/how-to-cast-on/ Below is some documentation of both of these things. The test walk in North Shields and Tynemouth resulted in me being caught out in a storm on the sea front, otherwise this walk would have been more circular. For now this is just logging ambient light for testing purposes while I await the arrival of the gas sensors from across the ocean.
A quick gnuplot of the sensor data against location can be found here: http://willschrimshaw.net/inv/plot.html
Potential code to be developed: conversion of gps log to knitting pattern/code such as:
