Check out this machinima. It's a music video to Flyleaf's So Sick(remixed version off the RE: Extiction sountrack). Extremely well done video. http://www.youtube.com/watch?v=hAOoRtPr5Kk Edit: my bad on teh link. not enough sleep.
Wow, that was pretty awesome, thanks for finally posting a link! XD Btw, did anyone else see Lev's name in the credits?
The syncing on that is pretty much faultless, and the direction is really good too. Amusingly it seems to have more views than the actual video does. Can't really compare it with too much other machinima because they have different genres, but as far as video game "music videos" it does make everything else I've seen look really lame.
