In one embodiment, a first perspective of a three-dimensional marker may be detected, where the three-dimensional marker has a shape that presents a different appearance from every angle. A first three-dimensional virtual overlay corresponding to the first perspective of the three-dimensional marker may be identified or generated. The first three-dimensional virtual overlay corresponding to the first perspective of the three-dimensional marker may be projected or displayed such that the first three-dimensional virtual overlay substantially covers the first perspective of the three-dimensional marker.
