Chinese artist Liu Bolin took the streets after literally being made homeless by the Chinese government. Suojiacun, an artists' village in northeastern Beijing was torn down during the Olympic redevelopment. An interview with WhiteHot Magazine can be found here.
With the help of assistants, Bolin has achieved a Metal Gear Solid 4 optic-camo level of camouflage by painting himself to blend in with the foreground. In a series he's called Hiding In The City, Bolin disappears into the urban landscapes of various cities. His photos haven't been touched by Photoshop and there's no camera trickery involved. The true meaning of his his art is up for interpretation, but if the first photo hasn't rattled your bones, you must have the eyes of a hawk.
