OK Go

This video clip has the most inventive choreography I've seen all day, at the very least. I can't think of anyone else who's out there exploring the choregraphic potential of the treadmill. These guys are a band called OK Go and they actually do play instruments and sing, just not in this video. They performed this same routine at the VMAs the other day. Go to youtube.com and search for their name to see their complete oeuvre.
