I posted on Sweza’s use of QR Codes to preserve graffiti for posterity and now London based interactive communications agency Digit is QR Coding graffiti before it gets erased! Everyone seems to have a different opinion about individual items of street art and this project, called I Could Do That, allows observers to communicate. Achieved by placing a QR code next to the art piece which links to a mobile site where viewers can have their say and also read what other people thought. The images below are graffiti by Grafter, just off Corbet place in E1. Here is an example of the comments for a Vhils work located in the Truman Brewery Car Park.
