I'm currently working on a project for uni that does something like this. It let's you "tag" items in the world. So, for example, I can leave a message on the painting on the wall. Next time I take a picture of that wall, it will show me my messages again. You could also use it to send messages to other people. "I left you a virtual message on the fridge." The other person walks up to the fridge, takes a picture, and gets the message. I think it has some interesting potential. It's on github [1]. Though I haven't created any video or documentation yet.
