Abstract
An optical illusion device such as a drinking glass/cup for providing a multi-dimensional visual display. The device includes a body with tubular sidewalls extending from an opening at a first end to an opening at a second end. A base assembly is provided at the second end. The base assembly includes a top wall, a bottom wall, and a sidewall that together form or define an inner chamber. A visual display assembly is provided with a mirror element with a convex reflective surface or mirror positioned within the chamber with the reflective surface facing the top wall of the base assembly. A primary image element is provided proximate to the reflective surface such that the primary image and mirror element can be observed via the opening in the body. A framing element is included proximate to the top wall of the base assembly including background images facing the reflective surface.
