Rubin’s Vase Illusion - Classic Figure-Ground Perception Example #1246718 (License: Personal Use)

This black-and-white image depicts Rubin’s vase, a seminal figure-ground illusion developed by Danish psychologist Edgar Rubin in 1915. The design cleverly uses negative space so that the white central shape appears as a chalice, while the surrounding black areas simultaneously resolve into two human profiles in profile view. It remains a foundational visual demonstration in cognitive psychology and Gestalt theory, illustrating how the brain organizes ambiguous stimuli into coherent percepts.

Used in psychology textbooks, cognitive science courses, design education, and UX discussions about visual perception; ideal for pages explaining optical illusions, Gestalt principles, or perceptual ambiguity.
