ABSTRACT:
A system wherein the observer can be positioned at the interior of a three dimensional display and observe the display looking outwardly therefrom. In accordance with a first embodiment of the invention, the rotating disk of the prior art is made sufficiently large and at sufficient angle, preferably 45 degrees with respect to the shaft rotating the disk, so that the observer or a camera can be located in a conical portion of the cylinder swept out by the disk wherein the disk does not travel. In accordance with a second embodiment of the invention, the rotating shaft onto which the disk is anchored is a hollow, transparent cylinder and is sufficiently large to retain a viewer or a camera within the cylinder. In this way, the observer can rotate 360 degrees within the cylinder to view the entire display looking outwardly from the interior thereof.
