I thought this was a cool concept. Alexandre Orion, a Sao Paulo based artist has created his pieces utilizing the pollution expelled directly from a truck exhaust. The process is not easy. If the truck bumps too hard, the piece will be damaged. And if it rains, the piece is totally ruined. For every 4 pieces he attempts only one makes it to final product. He calls this "Pollugraphies". The pollution is collected for one week. So disgusting and awesome.
