Graffiti Artist, Banksy, is almost as famous for his skill at anonymity as he is for his controversial art. He combines his unique stenciling technique with graffiti writing. He  has succeeded in tagging walls from Post Katrina New Orleans to the Palestinian segregation wall in the West Bank. This year at the  Sundance Film Festival,  Exit Through the Gift Shop, a feature about Banksy was debuted.

If you ever took a basic drawing class you may remember the practice of covering your paper with charcoal and then erasing it away to create your image (and always leaving smears of charcoal across your face). Well Reverse Graffiti Project takes this idea to a whole new level. They are erasing away the dirt on the city walls and turning it into a new form of graffiti art.
