The Myth of the Ivory Tower: Interest in street art

Recently I've started being interested in street art.  I have to admit, "Exit Through the Gift Shop" got me started, so maybe I'm band wagoning. I really don't care either way. I've always liked to walk the tunnels (for the non-Appstate folk out there, we have 2 tunnels you are allowed to tag), and see what was new.  I find it interesting the different ways people try to portray themselves through their art. Often it falls into the categories of: tag, fast art, or something well thought out. Typically the first two.
