I built a Dream Machine for Burning Man '07. It's since made trips to the Mojave Desert and a return to Burning Man in '08.
My two favorite quotes:
"Holy shit, that was trippy!"
– Random Burner
"Oh cool, cartoons!"
– Shutter*
The original installation was housed in a yurt, which in keeping with the '07 BM theme "Green Man," was made from bamboo and recycled billboards, with no screws or modern fasteners of any kind.
Some of the images in this article were supplied by Shutter. You can find more at her photo-blog "luna-See." Check it out for super awesome goodness.
