Rubin’s Vase Illusion - Classic Figure-Ground Perception Example #2041349 (License: Personal Use)

This classic Rubin vase illusion features two white profile silhouettes against a black background, with the negative space between them forming a symmetrical vase. First published by Danish psychologist Edgar Rubin in 1915, it exemplifies figure-ground segregation-a core principle in Gestalt psychology where the mind alternates between perceiving the profiles as foreground (figure) or the vase as foreground. The image remains ambiguous, inviting viewers to toggle between interpretations.
