I got a page not found error on the video. >.<
But for anyone who doesn't know, this is a spinoff of the arcade game Dance Dance Revolution, where you hit arrows on a pad with your feet to go with the arrows scrolling on the screen with music. It's a really popular arcade game in Japan and is catching on in the States too.
It's a lot of fun, a good workout if you're playing the hard levels.
Though IMO, the choreography on this flash site isn't nearly as good as the DDR arcade stuff. LOL
