I know that this video was around last year...but it's one you can watch over and over. And if you haven't seen it, watch it! I heard that it took 3 hours of work for each of the 9 seconds in the song.
Some local guy around here supposedly has one set to music. He said it's his first year and he's still experimenting. It didn't look as great on TV as this, but he did try! Maybe next year he can rival this one...then teach me how to do it.
