  • Patent number: 5247724
    Abstract: An anamorphic amusement device particularly suited for use by children while traveling, and who have access to a cup-retaining device normally used to prevent engaged cups containing a liquid from spillage due to upset. The device includes a cup of generally frusto-conical configuration having a reflective outer surface, and a planar orificed mat having an opening corresponding in diameter to that of a medial section of the cup. The device is used by inserting the cup through the orifice and positioning the lower end of the cup in a recess in the cup retaining device which thereby supports the cup and mat in proper relative condition wherein anamorphic images on the upper surface of the mat are viewed as undistorted reflective images on the reflective surface.
