The visual system fills in missing pieces of a shape to perceive it as whole. The Law of Closure is one of the original Gestalt principles, and it explains why a circle drawn with a small gap in its outline is still read instantly as a complete circle, not as an open arc. A well known logo built entirely from disconnected white shapes still reads clearly as the intended animal, because the mind supplies the missing edges automatically.
