ABSTRACT:
An apparatus and method are disclosed for viewing back lit and front lit depth images having different depth image scenes being projected at different viewer orientations. A rotatable frame is mounted to a stand for rotation about an axis, wherein the frame includes at least one viewing port. The frame includes a retainer for securing a depth image to the frame. An interior of the frame may be back lit to illuminate the viewing port. Alternatively, a projection system illuminates a retained depth image with an illuminating light at an angle of less than approximately 45.degree.. The frame is rotated about the axis by a drive assembly to present at least one cycle of information from the depth image to a stationary viewer.
