Simasticus

I forgot to mention this great project too.

Simasticus by Charles Earl Love Yust (USA)

Simasticus applies Sims game-play to the real world where actual people and the public play the role of Sims characters and the game player retains control in provoking interactions. They utilize Sims game iconography and parts of the useri interface to present a set of tools that a game player uses in achieving the goals of getting strangers to interact in a positive way.  This project has been successful in getting strangers to interact (and dance together) on the street using text messages and thought bubbles projected into public areas from elevated locations in nearby buildings.

Its really playful and really powerful although the films on the website don't show the project off to its best.
