Banksy. I could not get a picture of him for this board, since he is a secret, but here is some of his street art. I adore his work, but what I really love is the fact that he has not succumbed to the commercialization of art. He doesn't care about money or his own image, sometimes he doesn't even take credit for his work. All he cares about is getting his message across, and he certainly achieves that.
