A burning man installation with 13 flame speakers playing the voices of people who had talked to the art.
2400 computer controlled RGB lights, embedded in cast urethane, placed in a 800 foot diameter circle around the Man at Burning Man. This version has been out there since 2006. The entire system was built from scratch.
solar powered camper trailer
A small multi-use trailer for camping and field work. Has 600W of solar panels and 500AH of batteries. Insulated well enough for the roof AC to hold a 30 degree (f) differential with only 400whr from the power system. Very useful at Burning Man.
