I remember going to London years back and just being in awe of art just lining the streets. It was by no means scribble, but actual graffiti art. One artist in particular is now commercializing the once underground phenomena under the pseudonymous, Banksy. Banksy began his career as a freehand graffiti artist and then began to use stencils. His art speaks on politics, ethics and culture. He is currently screening his movie " Exit Through The Gift Shop" and I'm eager to see it.
