Augmented Reality (AR) certainly has practical uses, but it’s more often than not, used for some good fun. Now a Swedish magazine called T-post has launched a site where you can wear a special t-shirt, and coupled with a webcam, you’ll be able to play an AR version of rock-paper-scissors with the computer. As can be seen from the video, there will be a computer generated hand extending from the center of your body. If you think a t-shirt is too troublesome, you can always print out the PDF on a piece of paper and still pull it off, but somehow that doesn’t seem as cool.
