It's a little early for Christmas, but it's always the right time for dancing video game characters! Jan3D has put together a super-short video as an early holiday gift to his/her fellow gamers. And to think that you weren't planning on getting him/her anything.
Not much else to say here. Just be prepared to see Big Daddy, Nariko, Mario, Master Chief, Ratchet, and NiGHTS like you've never seen them before -- in sync.
