Graffiti, street art, personal expression — whatever you want to call it, the layers of history, artistry and beauty found on city street corners are undeniably compelling. When I see them, this happenstance artistic energy, I'm always fascinated at the time they were put up, the changes they've gone through and what they might become at my next visit. These walls of ours are constantly shifting in a creative, organic way.
