Motion aftereffect - Wikipedia, the free encyclopedia

The motion aftereffect (MAE) -is a visual illusion perceived after watching a moving visual stimulus for about a minute and then looking at stationary stimulus. The stationary stimulus appears to move slightly for about 15 seconds, opposite to the direction of the original (physically moving) stimulus. The motion aftereffect is believed to be the result of motion adaptation.

Here’s an example. Look at it for some time (say, 30 - 60 seconds), then look away. I can tell you, having your door wobble before your eyes can be a little creepy.
