Here's a YouTube video of six (intently focused) guys juggling Clapping Music by Steve Reich. As an ex-juggler I've known that there were rhythmic musical applications for juggling, but I never imagined anything like this. Very impressive.
This piece may be even more seminal because it can be adapted in such an unexpected manner, I suppose, but alas, it's no more interesting this way.

Here's a Steve Reich 70th Birthday video card I found on YouTube. "Music" performed in his "Style" on Two Pez Dispensers that look like Bert (or is it Ernie?)
