Methods, systems, and products describe physical structures for interactive computer displays. A tangible, three-dimensional structure has an interior and an exterior surface. A bundle of optical fibers propagates light through the interior to the exterior surface of the three-dimensional structure. A magnet in the three-dimensional structure produces an attractive force, and a marker on the exterior surface identifies the three-dimensional structure and the magnet.
