Rubin’s Vase Illusion - Classic Optical Illusion Explained #1933011 (License: Personal Use)

This image depicts Rubin’s Vase, a famous ambiguous figure-ground illusion where viewers alternately perceive either two black human profiles facing inward or a white vase centered on a black background. First published by Danish psychologist Edgar Rubin in 1915, it demonstrates how the brain organizes visual information into foreground (figure) and background (ground). The illusion remains widely used in cognitive science, art theory, and UI/UX design education.

Used in psychology textbooks, design courses, and neuroscience presentations to illustrate perceptual organization; ideal for pages about visual illusions, Gestalt principles, or cognitive biases.
