Heavy, Yet Light On the Feet: Dance Fortress
Do you remember pro-animator James Benson's dancing Team Fortress 2 characters? Of course you do.

James has finally finished the whole thing, which can be viewed below...
Though he urges and begs you to watch it full screen on max HD resolution. And I'll add that it's worth watching several times, just because there's so much detail on there. Hurrah!
