Rubin’s Vase Illusion - Classic Figure-Ground Perception Example #3853523 (License: Personal Use)

This iconic black-and-white image is Rubin’s Vase, a foundational example of figure-ground perception in Gestalt psychology. Depending on focus, viewers perceive either two silhouetted faces in profile or a white vase-shaped negative space between them. The illusion highlights how the human visual system alternates between foreground and background interpretation.

Commonly used in psychology, design, and education to demonstrate perceptual ambiguity and cognitive processing; ideal for articles on visual cognition, UX design principles, or neuroscience introductions.
