4T2 is a T-shirt that serves as a platform for content sharing in a physical, dynamic, and social way.
How does it work? The wearer of the shirt encodes a photo or a link that they would like to share into a personally designed barcode in the form of an LED pattern on the shirt. Others who see the shirt can use their smart phone camera and a decoding app to discover the message, react to it or copy it to their own T-shirt. This platform motivates a new kind of face-to-face discourse around content sharing in the real world.
