GRAFFYARD

I am using QR Codes to preserve graffiti for posterity by photographing the graffiti before it is removed. After the graffiti has been cleaned off by the local authorities or building owners i place a QR Code in the exact location which resolves to an image of the original. In that way a mobile phone with a QR-Code Reader can be used to travel back in time.

Get a QR decoder for IPhone or Android Phone here:
App Store for IPhone
Android Market
