Berlin graffiti artist Sweza has created an interesting take on street art. Since graffiti frequently gets buffed, Sweza has started taking photos of the art before they get removed. Once they are removed, he places a QR code at that location. Using his Graffyard iPhone app, users can retrieve an image of the previous graffiti on their phones. It would be interesting if multiple images are stored for the same location, if one could use Graffyard to travel back in time and see the previous graffiti in that location. Similar to the Eric Pakurar’s Chemical Warfare Project.

Yuri Suzuki proposes using graffiti QR codes to promote pirate radio stations. Instead of broadcasting over the air, the audio is streamed directly to the phone whenever someone follows the QR code.

I would think one of the joys of running a pirate station is the overt illegality of it. Granted the FCC doesn’t often go around shutting down even prominent stations. (Except of course, when they do), but simply streaming over the Internet is like setting up a blog that no one reads. (*cough* *cough*)
