Rubin's vase

Rubin's vase is a famous optical illusion that can be seen as either a vase or two faces in profile. It illustrates how our brains interpret visual information, allowing us to switch between different perspectives. When you focus on the white shape, you see a vase; when you focus on the black space, you see the faces. This effect demonstrates the duality of perception, showing how context and interpretation influence how we understand images. Rubin's vase is often used in psychology and art to explore concepts of figure-ground perception and visual ambiguity.
