Reverse Graffiti

Reverse graffiti is a form of graffiti that is created by drawing with a cloth (or other cleaning tool) on a very dirty surface, rather than with a spray-paint can. In doing this, the art ends up etched into the filth and calls attention to the pollution in the area. Grafitti artist Orion transformed the Max Feffer Tunnel in São Paulo, Brazil into one of the most spellbinding works of street art. He created a mural comprised of hundreds of macabre skulls. Alexandres message here was quite clear; drivers in the area needed to do something about their emissions. If a tunnel is turned into a soot and grime filled chimney of sorts, imagine how the rest of the Earth is being impacted. Although the police showed up a couple of times, they could not charge him with a crime since he was not doing anything illegal. In the end, the police contacted city officials and eventually the tunnel was cleaned.
