Description: Illustrates, through the use of animation and special effects, how the human eye views an object and how the brain perceives distance, perspective, and movement. Uses over twenty visual illusions to explain the illusion of depth, diversion, extent, after-image, reverse relief, and perceived movement. Illustrates the size variance related to the vertical-horizontal positioning and gamma movement caused by variation in light intensity.
