It's always great to come across unusual and inspiring green art projects. Have you ever heard of "reverse graffiti"? Neither had we until recently.
Reverse graffiti is when you take filthy, moss covered surfaces and wipe away the dirt to create amazing green artworks.
UK artist Paul Curtis, or Moose as he calls himself, is a reverse graffiti artist. It involves no paint. No defacing. Moose makes his art by cleaning; removing the evils of dirt and pollution by wiping it away.
Below are a few examples of Moose's work. Looking at makes us want to invest in some cloths and a bucket to fill with water and head out in the London streets.
