The Creative Class: Reverse Graffiti

Huffington Post has a really interesting post about reverse graffiti, also known as clean tagging or grime writing.

Reverse graffiti is form of street art that involves carving into the dirt and dust that surrounds us. Artists subtract from a surface in order to create a negative image within the positive, often quite dark layer of grime.They use methods as simple as dragging their finger across a dirty car window or as elaborate as carving elaborate stencils, which they then mount on a surface and spray with a high pressure water hose, to impress a finely wrought illustration or message. Reverse graffiti is a form of activist art, in that the work often draws attention not only to a particular image etched into a surface, but also the extent to which these surfaces - and our cities - are caked with pollution.
