Reverse graffiti also known as clean tagging, dust tagging or grime writing, is a method of removing dirt from a surface while creating graffiti on walls or other surfaces. It is usually done by removing dirt/dust with the fingertip(s) from windows or other dirty surfaces. Reverse graffiti on windows/glass can be highly visible due to the reflection of sunlight. Due to the lack of paint it is often used for Advertising, and companies such as Microsoft and Smirnoff, have had their products advertised this way. Ironically the UK pressure group Keep Britain Tidy are against reverse graffiti.
"The skulls belong all to us. I wanted to bring a catacomb from the near future to the present, to show people that the tragedy of pollution is happening right now. I try to remind people of things they are trying to forget." - Alexandre Orion.
