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, also known as motion illusion or "apparent motion", is an optical illusion in which a static image appears to be moving due to the cognitive effects of interacting color contrasts, object shapes, and position.

This result suggests that the bottom-up cues that drive the flicking response are distinct from the top-down cues that drive the Hollow-Face illusion. Another example of the Hollow-Face illusion is the "Gathering 4 Gardner" dragon. This dragon's head seems to follow the viewer's eyes everywhere (even up or down), when lighting, perspective and ...
The Moon illusion is an optical illusion in which the Moon appears larger near the horizon than it does while higher up in the sky. Motion aftereffect: Motion illusion: Müller-Lyer illusion: The Müller-Lyer illusion is an optical illusion consisting of a stylized arrow. Multistable perception: Necker cube
Optical illusion is also used in film by the technique of forced perspective. Op art is a style of art that uses optical illusions to create an impression of movement, or hidden images and patterns. Trompe-l'œil uses realistic imagery to create the optical illusion that depicted objects exist in three dimensions.
In this illusion, two figures that are identical (i.e. the two train track segments) appears to be different sizes while lying perpendicular to each other on a flat surface -- the lower one ...
In visual perception, the kinetic depth effect is the phenomenon whereby the three-dimensional structural form of an object can be perceived when the object is moving. In the absence of other visual depth cues , this might be the only perception mechanism available to infer the object's shape.
There are everyday examples of hidden faces, they are "chance images" including faces in the clouds, figures of the Rorschach Test and the Man in the Moon. Leonardo da Vinci wrote about them in his notebook: "If you look at walls that are stained or made of different kinds of stones you can think you see in them certain picturesque views of mountains, rivers, rocks, trees, plains, broad ...
Furthermore, moving one's eyes away from the image after a period of time may result in a brief, strong afterimage of a circle of green spots. Troxler's fading , also called Troxler fading or the Troxler effect , is an optical illusion affecting visual perception .
