I've had this link floating around for about five years now and never got a chance to post it. So here it is. Hyperfabric, created by the HMC Medialab, is a touchable interface that uses a very thin film to simulate an immersive user interface.
You can press, grab, twist, punch and play with the screen. It can even support your full bodyweight. The Hyperfabric screen is specially designed to communicate with a computer to generate interactive computer graphics, in realtime.
Images are projected onto the film that react to touch and pushing, so it feels like you're actually pushing through the image. The resulting coolness, which must look great while stoned, doesn't have many practical implementations yet, but it does appear to be an interesting potential interface system.
