The Necker cube is an optical illusion first published, as a rhomboid shape, in 1832 by the Swiss crystallographer Louis Albert Necker. It is a simple, wire-frame, two-dimensional drawing of a translucent cube that carries no visual cues indicating its true orientation, so the viewer's visual system can interpret either the lower-left square or the upper-right square as the cube's front face; most viewers experience their perception spontaneously flipping back and forth between the two interpretations the longer they look at the figure, making it a classic early example of an ambiguous, bistable image used to study visual perception.
