Caption: Hollow-face illusion, animation. This is an optical illusion where the perception of a concave (hollow) mask of a face appears as a normal convex (protruding) face. This is because the brain has a strong bias for seeing faces as convex, which counteracts competing depth perception information, such as highlights and shadows.
