Sundance ended today, and I have yet to see "Exit Through the Gift Shop," the world's first "street art disaster movie."
Banksy is a London based Graffiti artist, specializing in something called stencil art, which is exactly what it sounds like. You make a big stencil and some layers , then tape it to a wall and spray paint over it. A few examples, here. Banksy is this huge enigma of a man, in that virtually no one knows what he looks like. One cloudy London day, you have a blank brick wall, and in the blink of an eye, at the perfect moment in time when everyone seems to be turned the other way, he strikes.
