Golan Levin writes software that he uses for performance art. The movements he creates with the mouse/tablet are reproduced by the software as looping animations and sounds. It's like a very literal language that bridges video and audio.
The loops he creates in this video seem pretty simple and aren't particularly aesthetic, but this opens up some really interesting doors as to processes that can synthesize sight and sound.
TED stands for Technology, Entertainment, and Design. It's a series of lectures held in Monterey, California, and the best of the lectures are posted online for free. Homepage: [link]
