Drum arcade makes it on stage

I've been writing Masayuki Akamatsu fan letters, since I found his akaRemote software so useful, and thanks to my SuperCollider classes for his interface I got a mention on his blog, which was cool. I wrote to tell him of my idea for putting arcade players on stage: having witnessed a "drummer" in a Kyoto arcade playing with an incredible degree of accuracy, I figured it would be possible to make a whole band of players following game-style falling blocks, programmed according to my music, and playing as robotically as any machine (95% of my music is rigidly quantised - I see it as part of the challenge to make the expression come from other elements.) He wrote back to link me to a video of his 2001 piece "Pray For Rain" which uses a very similar idea.
