I've dabbled in air brushing a while ago and it's a tough little thing to do well. For the artist below to craft a sweet Crysis 2 mural for the game testing room this way in NVIDIA's Moscow office, it's pretty damn impressive and the guy's got some great talent. I'm actually thinking of doing something like this in my kid's room, but I'll just regular paint. Check out the time lapse video of the masterpiece coming to life.
