This guy apparently created an entire VHS tape full of Coco-created 
videos that was frequently played at Emo's, a fairly well-known Texas 
bar and venue for live music.  Cool stuff!

I've actually toyed with the idea of trying to create an 
iTunes-visualizer-esque program for the Coco.  I've written several 
little programs that create abstract patterns on their own, of 
course, but it'd be fun to do something that might respond to the 
amplitude of an audio signal -- presumably via the joystick port?
