Here's a music video made my synchronizing Soul Calibur with a dance track:
Music video made with Soul Calibur video game footage
Dance, Voldo, Dance is a music video made by synchronizing the movements of gladiators from the game Soul Calibur with a dance track, so that they appear to be getting down with their nasty selves to the music. It's quite good!

There's also notes about it linked to from the video. Pretty cool.
