Reverse Graffiti by Moose - People need to realise how dirty this world is.
Just found this reverse graffiti video, sending a message to people of the world that how dirty this world is. Reverse Graffiti is done by cleaning the dust at the wall, and making a mural out of it. I've seen another reverse graffiti video who use wet cloth to draw while stenciling was use in this one. You watch carefully the drips of water itself wont actually clean the dust, you could imagine how dirty it is. http://www.reversegraffitiproject.com
