The mechanics of parallel projections are inconsistent, however. Two figures may appear to have the same size while they might be fifty units apart in distance, and thus, people become flummoxed when they want to interpret depth when in a projection that strips itself of depth. The lack of depth in parallel projections makes it not only marvelous for technical drawings but also creative drawings. If people cannot tell how close two figures are, then the artist can purport that it can be interpreted in both locations in space. Video games, in particular, exploit this property, and, most famously, M.C. Escher employed parallel perspective extensively in his artwork:
