Art is dirty. I’ve seen a few clever ideas that use the removal of dirt and grime to create something new, but I particularly like Simon Heijdens’ ‘Clean Carpets’ project. Through the use of a high-pressure sprayer and a template, grime is removed from the pavement in the shape of a carpet. The clean spot appears, a place where one would want to sit. The image is made by taking away instead of adding. The carpet slowly disappears over time as the streets gathers fresh grime.
