Online Virtual Graffiti?!?!?!?!

Promoted and represented by Sprite and MSN is a site where you can do your own "stencil graffiti." It's called Refreshing Wall (I know, how bad is that name). I'm not promoting it, I just want to expose the stupidity and utter ridiculousness of it. How far should corporations go with their advertising campaigns? The answer is a double-edged sword. Then you have to ask yourself: How far should artists go with their art? It's obvious that we are biased to one of those. just thought I'd throw out those thoughts.
