The Siftables are quite interesting. They are an information interface that is supposed to be more physical and natural. The analogy they use is a container of nuts and bolts can be sifted through quite easily using your hands. They envision us being able to sift through data similarly. They also mention that it could be used as a gestural interface as well.

Each unit is a small device with a screen, wireless communication, and IR sensors. There are some pictures of the units in action as well as a video on their site.
