My friend Dev -- founder of Fate of Io -- entered a Machinima contest. The goal was to use World of Warcraft to create a music video to go with one of three songs by The Ataris (some rock band).

I think he produced an amazing video:

He was selected as one of the ten finalists and is currently leading the voting:

If you have a chance, check out the other finalists and vote. The video by Dead Workers Party is also pretty good (and is in second as of this writing).
