Artists create amazing "reverse graffiti" car art using pollution and a power washer

In fact, the pair have teamed up to create our favorite kind of art – the sort that features automobiles as the subject. Starting with a spot on a dirt-covered wall in Munich, Moose and Cameron remove the buildup of gunk in various layers leaving behind their desired image.

It's called "reverse graffiti" or "grime writing," and rather than covering a wall in paint, Cameron and Moose actually clean a portion of the area they're working on. Some stencils, a few helping hands and a high-pressure power washer are the tools at work, and the resulting image not only illustrates how polluted public surfaces can be, it's also wonderful spin on a form of art that's typically frowned up.

Watch a reverse graffiti Tesla Roadster come to life, a project Cameron and Curtis coordinated with German's SZ-Magazin.
