ABSTRACT:
An optical illusion device consisting of a three section backmember, one end section being larger and having features proportionally larger than features common to the smaller end section and positioned proportionally farther distance from a vertical plane in front of the three section backmember and parallel to the end sections. Each of the end sections has its own level floor on a horizontal plane at right angles to the plumb and is sized to accommodate a person thereon. The floor of the larger end section is on a lower plane than the floor of the smaller end section. Viewers' eyes are positioned along the vertical plane at one or more viewing peepholes. The larger and smaller end sections are adjusted vertically in relation to each other so that sight lines from the peepholes to be common features in the two end sections lie on a plane that is level from the viewers' left to right. An interconnecting center section has dimensions that match the larger end section where they come together, but decreases in size and angles forward to the degree necessary to match the dimensions and come together with the smaller end section. When viewed through the peepholes, the three sections appear to be equidistant from the viewers.
