The site where the BM art festival takes place is a dried out lake bed, which is exceptionally flat, with very few obstacles. The inflatable form took 3 days to build. A test inflation of the pillow in the campground went smoothly providing a structure which was 40 feet long x 30 feet wide x 16 feet high. The pillow was inflated once a day and released to roll down the desert and was gently pushed along by the wind. Typically a group of cyclists followed the pillow often dropping their bikes to grab the membrane and surf behind it.
