Augmented reality is truly awesome, but unfortunately it hasn’t found a wealth of practical applications just yet. That is, until now. In cooperation with Swedish “wearable magazine” T-post, offbeat designer Marc Stromberg created a t-shirt that allows wearers to play a virtual game of rock paper scissors with an animated hand coming straight out of their chests.

All you need to do is put on the shirt, then go to the game page and make sure your webcam is turned on. Your image will appear on the screen, along with the creepy animated hand that will challenge you to what will probably be the weirdest game of rock paper scissors you’ll ever play. Of course, if you don’t have the t-shirt you can print out a PDF file that will achieve the same thing…but that does seem slightly less fun.
