Since its creation in 2007, the Facebook application, Graffiti Wall, has spawned 70,000,000 works of digital graffiti from amateur artists around the world. Now, the company behind the app has launched a website where people can purchase some of the designs as prints. The application only allows the use of color, width and opacity, so some of the works are pretty damn impressive when considering its limitations.
