Hmm, that's actually really cool. Did you check out all the varations?
I've always been fascinated by the visualization of audio and the audioization (ok, not a word
) of visuals. I remember a guy named Golan Levin who did some really amazing work at MIT with similar kind of stuff: http://www.flong.com/
The "Audio Visual Environment Suite" and "Scribble Performance" are the things to check out. Not sure if the videos are on there anymore, but he has a lot of other cool projects (like a font synthesis system) that are worth checking out too. I presume YouTube or Google Video have mirrors of his stuff too, if it's not there anymore. Hmm, yep http://youtube.com/r...in&search=Search
