Motion from occlusion.
Vision uses specific image features or cues to infer physical properties of the world. Here, we use a novel illusion to show that occlusion, traditionally thought of as a cue to depth, is also a powerful cue to motion. A display of stacking disks that contains only occlusion as a cue to depth generates a vivid sense of movement that is likely computed in early or middle levels of visual processing.
