Some pictures of the jigsaw puzzle I made for Burning Man '09.
The puzzle measured about 8ft x 6ft 8in, and was 30 pieces (6x5). On the back of each piece, I wrote the address of our camp, Want It. 10 of the pieces I distributed at various art installations around the playa (with the artists' permission), so that people could bring them back and fit their piece into the larger puzzle. 7/10 were successfully brought back and re-included.
The inner-to-outermost spiral in the design is based on a Fibonacci spiral.
