I love this concept – graffiti created by removing dirt. Just to be clear, these practitioners are removing the dirt, not applying anything. It’s a wonderful idea and a poignant statement about the condition of our world. Businesses have also been using it for advertising. Of course if you have ever written “wash me” on a car, you are a practitioner too!
Here is a video about making one with the man who is credited with starting the movement.
