*'s on the ball. Mindless tagging is often pretty bad but well done graffiti be it a stencil or a mural gives an area character,imagine if every city had a large public area where is was ok to spray, a constantly changing wall of art.

not to mention thats its a starting place for some of the best graphic designers around.

check out the documentary Rock Fresh.

P.S Banksy's kind of sold out, he sold this http://img79.imageshack.us/img79/8816/angelinajolie074ltr2.jpg to Angelina Jolie for $75,000, unless he comes out in a few months and says he gave the money to charity and it was all "art" he's pretty hypocritical.
