Two years ago, MIT's Tangible Media Lab demonstrated the inFORM project, a "dynamic shape display" that, through a series of pins and actuators, could physically change shape in response to the user interacting with it. Put simply, it was like a 3D screen that could give data a physical form. MIT has since pushed that technology further with the new Kinetic Blocks project, which uses pin "pixels" to build simple structures out of blocks.
