That's great! There's a making of video floating about too.

OK Go also has a great video with a marching band and camouflage suits.
wow ... that is amazing ... the amount of time that it must have taken them to get everything set up perfectly to do that ... my mind boggles at the brain power behind those things.
OK Go does really fun videos - I like their treadmill one (which appears briefly on the tv screen in this one before it gets smashed)
We had a piano like that when I was growing up. I never thought of doing *that* to it. Hmm...

Although it was hard enough keeping it in tune.
