Reverse Graffiti

Alexandre Orion of Sao Paolo etching skulls on the side of the tunnel with nothing but water and a cloth.
This is a really interesting concept, although far from real graffiti--and perhaps even frowned upon by some hard core writers. Awesome stuff, too bad it's so temporary, his work only lasts for a couple of minutes/hours, but than again so do most of the train pieces before they get buffed.
