Scannable Graffiti Acts Like A QR Code

Developed by Jeremy Rubin and Andrew Lippman from the Viral Spaces group at the MIT Media Lab, ‘Graffiti Codes‘ enables users to encode small pieces of information into a physical space, similar to a QR code. It uses accelerometer-based paths to unlock data, which can be drawn onto any surface with tools such as markers. They can then be scanned by tracing over them with a mobile device and the Graffiti Code software converts the image into code that links to a webpage.
