This is known as "The Invisible Man". My question is, do you have the patience to get painted, so that you blend into the background?
Normally, Lui Bolin is behind a camera, but he has come up with a concept of art by painting himself, so that he becomes his surrounding. He has blended into magazine racks, TV screens and even stages in front of amazed crowds.
He has an interview on TED that has been getting a lot of attention, and the video of how he does it can be seen on Vimeo (and seen below)
