Contour rivalry

This article is about a technique of art. See binocular rivalry for information about alternations in visibility of different contours presented one to each eye.

Contour rivalry is an artistic technique used to create multiple possible visual interpretations of an image. An image may be viewed as depicting one thing when viewed in a certain way; but if the image is flipped or turned, the same lines that formed the previous image now make up an entirely new design.
