"Ossario" is a cool intervention by Sao Paolo reverse graffiti artist Alexandre Orion to protest against our passive acceptance of pollution. He creates his images by removing soot from the walls - effectively cleaning the surfaces he draws on. Brazilian authorities at first reacted by cleaning only the part he had worked on - he simply kept on drawing on the other side. Apparently authorities then took more drastic actions by cleaning all of the towns's tunnels... Mission accomplished I guess.

On a lighter tone also check out Scott Wade's Dirty Car Art gallery.

Bandit is a Spanish street artist I recently had the chance to meet. I am glad I did so as to me some of his creations are up there with some of Banksy's best works.
