Have you ever played a rock-paper-scissors game with your T-shirts?

Here is an interesting video clip showing one use for augmented reality. Augmented reality has become more and more intelligent. It is not only showing virtual objects but also it can communicate between virtual objects and humans. I think this could be the future of augmented reality.
We could improve this application by making it more realistic. In the real world of course we play face-to-face. One improvement could be for one player to wear the T-shirt while the second player wears the augmented reality goggles and plays against the first player's T-shirt.
