The Reverse Graffiti Project
This video first surfaced in 2008 and could qualify as "throwback Thursday" material. The self proclaimed "Professor of Dirt" Paul "Moose" Curtis and crew took to the streets of San Francisco as part of the Reverse Graffiti Project creating beautiful images throughout the city by cleaning dirty walls with pressure washers and stencils instead of tagging them with spray cans and acrylic. It was later revealed that the project was part of an ad campaign but no hating from this end. Advertising or not, it just goes to show that the tools of artistic expression are not limited to only paint and canvas.
