Ambiguous images flip between interpretations and cannot be seen both ways at once

Gestalt multistability occurs when a visual stimulus supports two or more valid perceptual interpretations and the viewer oscillates between them, unable to hold both simultaneously. Classic examples include the Necker cube and the ‘young woman / old woman’ illusion. Once a viewer locks onto one interpretation it is difficult to unsee. For visual artists and interaction designers this is a tool: ambiguity can be exploited for aesthetic tension (generative art, op art) or avoided (interfaces should not multistabilise unintentionally — a button that could be read as a label causes errors). Multistability is distinct from figure/ground: figure/ground is about depth ordering; multistability is about semantic interpretation.

Examples

Rubin’s Vase: white figure on black ground reads as a vase OR two faces. Necker cube: the ‘front’ face swaps between lower-left and upper-right with viewing time.

Assessment

Find three logos or icons that exhibit multistability, describe both readings, and explain whether the designer likely intended this or not.
