Although I like the concept and think it looks nice, the awe-inspiring thing about this demo is that it all - music and visuals and everything - fits into 64k. This demo is also a heaven for curious people since it comes with more than the usual background information: David Geier, a member of Brain Control[a], the demo group behind Turtles All the Way Down, wrote an extensive making-of about it[b], and if you go to the Brain Control homepage[c], you can download the source code to it.
