Claim Text:
1. A method that comprises passing an illumination beam through each hologram, respectively, in a plurality of horizontal-parallax-only (HPO) holograms, such that different holograms in the plurality are illuminated at different times, and such that the holograms display an animated movie of a scene, wherein: (a) the holograms are vertically displaced from each other on a hologram recording medium; and (b) a first hologram, out of the plurality of HPO holograms, displays a first image that shows a first vertical perspective on the scene, which first vertical perspective is the vertical angle from which the scene appears, in the first image, to be shown; (c) a second hologram, out of the plurality of HPO holograms, displays a second image that shows a second vertical perspective on the scene, which second vertical perspective is the vertical angle from which the scene appears, in the second image, to be shown; and (d) the first and second vertical perspectives are identical to each other, even though content of the first image differs from content of the second image in at least some respects other than vertical perspective.
