This one is actually already old news, but I recently discovered it via Drawn.
Codehunters is a sci-fi/western anime hybrid short developed by UK’s Blinkink for MTV Asia. The style and the animation are really gorgeous, you almost don’t realize it’s all CG.
I’m still downloading the whole thing, and you can do the same by clicking here, but if you can’t wait for all the 147MB to download, go watch it online at the official site. Actually, this was done in 2006, so it’s probably that all of you already knew about this sweet short, and I’m the last person on Earth to discover this gem. Oh well!
