There are quite a lot of people who've done similar things to the daft hands thing (just check the list of "related videos" on youtube). I thought this was a bit more original than just copying the first one. And while on the topic of dancing to Harder, Better, Faster, Stronger there's this video which is pretty good (it's recorded on half-speed). Or why not check out some neat popping and locking with Hilty & Bosch, the Daft Punk bit starts at about 4:20.

If you just want to hear an a capella version instead of all this dancing madness: here you go.
