Abstract
A toy figure having artificial eyes which when viewed by an observer, create, as a result of an optical illusion, apparent eyeball movement as the observer changes his orientation relative to the figure. Each artificial eye is constituted by a case formed of a transparent sphere or truncated sphere having a ball supported concentrically therein to simulate an eyeball. The artificial eye is mounted on the head of the figure to expose its convex frontal section, this being covered by a mask having a window therein which displays the eyeball and the regions above and below the eyeball and those on either side thereof. As a consequence, an observer looking at the artificial eye in a direction normal thereto in alignment with the eyeball center sees the eyeball in its centered position. But as the observer changes his position relative to the figure and views the eye through the window in a direction at an angle to the alignment direction, then the eyeball appears to be displaced from its centered position upwardly or downwardly or to one side thereof to an extent that depends on the angle of view, whereby the eyeball seems to follow the observer's movement.
