blogumenta - an exhibition in facebook

http://www.facebook.com/group.php?gid=2380698481 (you have to be a member of facebook to see this) Or there's documentation of the project at http://www.blogumenta.com/

From the Facebook group page:
"Blogumenta may be Facebook’s first art gallery/art fair. Anyone can join and submit an artwork by uploading a photo or writing on the wall or any other way you can think of to contribute."

I'm not sure whether, out of all the social networki sites available, facebook is the one most suited to this - the implication is that you have to be a member to join in or even just visit the exhibition, while the open-access blogumenta.com is described as documentary evidence rather than an actual experience.

It's also interesting that this project is basically a response this year's Documenta - a real physical happening
