The Kanizsa Illusion II Stare at this figure until a white star appears in the center. The star is a "subjective" star. It is subject to the whim of the eight "PACMAN" faces, since they define its shape, and its very existence. Change the
shape of the star by using the slider bar to
open and close the "PACMANs" mouths.
