Burning Man 2010 - LoopyCart
This was my ninth year in a row. I built LoopyCart - an 8' trailer with a battery-powered projector and projection screen (visible from both sides). I pulled the trailer behind my bike, stopping at various locations (usually the large sound camps at 2 and 10 o'clock) to entertain folks with LoopyCam, often with Claudine Naganuma's dancing providing the visual input.
Pictures taken during the event are here.
