This was a Burning Man version of the Machine Control Experiment. Myself and other members of the theme camp built a 45-foot diameter structure in the desert and hosted lots of test subjects. We got a video projector running off of car batteries for the animated parts of the experience, and coped magnificently with large-scale dust and wind. It was a lot of fun.
To get an idea of what the camp looked like, have a look at Bradley R. Milton’s very cool panoramic photos.
