Reverse graffiti is a method of creating temporary or semi-permanent images on walls or other surfaces by removing dirt from a surface. It can also be done by simply removing dirt with the fingertip from windows or other dirty surfaces, such as writing "wash me" on a dirty vehicle. Others, such as graffiti artist Moose, use a cloth or a high-power washer to remove dirt on a larger scale.

Street art is visual art created in public locations for public visibility. It has been associated with the terms "independent art", "post-graffiti", "neo-graffiti" and guerrilla art.
