The more I learn about graffiti art, the more I appreciate it, and my interest in it started with Banksy about 4 years ago. He has a new psuedo-documentary out called Exit Through the Gift Shop, and it looks excellent. It has already been released in select theaters and I can't wait until it makes it to Calgary. Personal side note - when I was living in New York in Soho, my building had a Space Invaders mosaic on it.
