The Droste effect (Dutch pronunciation:), known in art as an example of mise en abyme, is the effect of a picture recursively appearing within itself, in a place where a similar picture would realistically be expected to appear. This produces a loop which in theory could go on forever, but in practice only continues as far as the image's ...
The Ternus illusion (1926/1938) is based upon apparent motion. Thaumatrope: A thaumatrope is a toy that was popular in Victorian times. Trompe-l'œil: Troxler's fading: Troxler's fading: When one fixates on a particular point for even a short period of time, an unchanging stimulus away from the fixation point will fade away and disappear ...
Billboards and other electronic signs use apparent motion to simulate moving text by flashing lights on and off as if the text is moving.. The term illusory motion, or motion illusion or apparent motion, refers to any optical illusion in which a static image appears to be moving due to the cognitive effects of interacting color contrasts, object shapes, and position.

The most well-known version of this illusion is known as the stopped-clock illusion, wherein a subject's first impression of the second-hand movement of an analog clock, subsequent to one's directed attention (i.e., saccade) to the clock, is the perception of a slower-than-normal second-hand movement rate (the second-hand of the clock may ...
Once this is done, the images around the matched patterns quickly become clear as the brain matches additional patterns using roughly the same degree of convergence. A type of wallpaper autostereogram featuring 3D objects instead of flat patterns The bottom part of this autostereogram is free of 3D images. It is easier to trick the brain into ...
Chronostasis (from Greek χρόνος, chrónos, 'time' and στάσις, stásis, 'standing') is a type of temporal illusion in which the first impression following the introduction of a new event or task-demand to the brain can appear to be extended in time. [1]

A 3D-printed version of the Reutersvärd Triangle illusion. M.C. Escher's lithograph Waterfall (1961) depicts a watercourse that flows in a zigzag along the long sides of two elongated Penrose triangles, so that it ends up two stories higher than it began. The resulting waterfall, forming the short sides of both triangles, drives a water wheel.
