Graffity street art

It's hard to imagine that a simple, stenciled picture on a wall could inspire so much praise and criticism. There are views in both of the extremes ranging from embracing the art as part of the city it is located in to writing the images off as nothing other than illegal tagging, but one thing is for sure: artists like Blek le Rat and Banksy have managed to make huge names for themselves and stencil graffiti as an art form around the world.
