A gallery of walls
Some people would argue that graffiti is not art. I disagree. In fact, I would go as far as to say that it might be one of the truer art forms. Art should be created for art's sake. Creating art for with a motive taints it. Even creating art to have, at the end, the end result of that process takes away from the process itself. On one episode of "Northern Exposure", one of the characters, Chris, argued that you should destroy the material object that is created because it's not about that object, it's about the process. Perhaps graffiti isn't as unencumbered as it could be but at least it isn't encumbered by the burden of the influence of wanting to sell what you've created. On the contrary, with graffiti, the thing that is created is often reviled and shouldn't all great art incite scorn? Either way, graffiti can often give us insight into ourselves as a society; or, it can simply make us laugh. One site has set out to catalog a variety of messages displayed on walls. Decide for yourself whether it's art or merely an act of vandalism.
