Graffiti Research Lab on KPN Tower, Rotterdam

In 2007 The Graffiti Research Lab took control of the KPN Building, one of the permanent media facades, turning the area into the People´s Revolutionary Green Laser Light District, a place to display your uncurated animations and graphics. The back-side of the building is becoming a giant wall you can write on with a BFL (big fucking laser).
