The wagon-wheel effect (alternatively called stagecoach-wheel effect) is an optical illusion in which a spoked wheel appears to rotate differently from its true rotation. The wheel can appear to rotate more slowly than the true rotation, it can appear stationary, or it can appear to rotate in the opposite direction from the true rotation ...

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 ...
The illusion derives from the lack of visual cues for depth. For instance, as the dancer's arms move from viewer's left to right, it is possible to view her arms passing between her body and the viewer (that is, in the foreground of the picture, in which case she would be circling counterclockwise on her right foot) and it is also possible to view her arms as passing behind the dancer's body ...
Psi wheel example. There are several designs for the shape of the psi wheel, but the most common is an inverted funnel-shaped pyramid. This psi wheel shape may be constructed by creasing a small (around 2 inch by 2 inch) square of paper or foil lengthwise, height wise, and diagonally both ways, then bending the square slightly along the creases to reach the desired shape.
The phenakistiscope (also known by the spellings phénakisticope or phenakistoscope) was the first widespread animation device that created a fluid illusion of motion. Dubbed Fantascope and Stroboscopische Scheiben ('stroboscopic discs') by its inventors, it has been known under many other names until the French product name Phénakisticope ...
Illusion similar to Rotating Snakes. Rotating snakes is an optical illusion developed by Professor Akiyoshi Kitaoka in 2003. [1] A type of peripheral drift illusion, the "snakes" consist of several bands of color which resemble coiled serpents. Although the image is static, the snakes appear to be moving in circles.
The Spinning Dancer is a kinetic, bistable optical illusion resembling a pirouetting female dancer. The dancer can be seen to be spinning alternately one direction, or the other. 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.
