Popcode makes augmented reality t-shirt games you can play on your phone.

Fastcompany reports on an augmented reality t-shirt app, which is cute, funny and will be used in advertising in 5....4... 3... 2.. Oh wait, has it already? The T-shirt magazine T-post made an augmented reality t-sirt that played rock paper scissors last year. Maybe that doesn't count, but I'm pretty sure a hip brand will be throwing themselves on the phone to make a fun t-shirt like this soon.

Researchers at Cambridge University have developed a cool augmented reality app called Popcode. An update to the app recently made it available for iPhone 4 and Android, and the app is being featured at the University of Cambridge Science festival being held this week and next.
