This invention is a device for displaying images that appear to be three-dimensional, with binocular disparity and motion parallax, for multiple viewers in different viewing locations. This device includes an array of display elements wherein at least one of these display elements includes: one or more light-emitting members; and two or more rotating concentric light guides whose rotation guides the directions of the light rays from the one or more light-emitting members. This invention has several advantages over methods for displaying three-dimensional images in the prior art. It offers a wide range of motion parallax in different directions for multiple viewers, does not require glasses or head tracking, creates images with full potential for opacity and occlusion, and does not require coherent light.
