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