The wagon-wheel effect is most often seen in film or television depictions of stagecoaches or wagons in Western movies, although recordings of any regularly spoked rotating object will show it, such as helicopter rotors, aircraft propellers and car rims. In these recorded media, the effect is a result of temporal aliasing. [1]
Colour distribution of a Newton disk. The Newton disk, also known as the disappearing color disk, is a well-known physics experiment with a rotating disk with segments in different colors (usually Newton's primary colors: red, orange, yellow, green, blue, indigo, and violet, commonly known by the abbreviation ROYGBIV) appearing as white (or off-white or grey) when it's spun rapidly about its axis.
It features 25 tricks that include an optical illusion (a nice segway to talking about our brains), special contraptions (like a box and drawer that makes crayons vanish and reappear), and of ...
Example movie which produces distortion illusion after one watches it and looks away. The motion aftereffect (MAE) is a visual illusion experienced after viewing a moving visual stimulus for a time (tens of milliseconds to minutes) with stationary eyes, and then fixating a stationary stimulus. The stationary stimulus appears to move in the ...
A zoetrope is a pre-film animation device that produces the illusion of motion, by displaying a sequence of drawings or photographs showing progressive phases of that motion. A zoetrope is a cylindrical variant of the phénakisticope , an apparatus suggested after the stroboscopic discs were introduced in 1833.

The quest to achieve longer and longer spin times led him to invite MIT professor Peter Fisher onto the show to experiment with the problem. Spinning the ring in a vacuum had no identifiable effect, while a Teflon spinning support surface gave a record time of 51 seconds, corroborating the claim that rolling friction is the primary mechanism ...
