The spinning dancer is a kinetic, bistable optical illusion resembling a rotating female dancer. The Spinning Dancer, also known as the Silhouette Illusion, is a kinetic, bistable, animated optical illusion originally distributed as a GIF animation showing a silhouette of a pirouetting female dancer.
The brain may give up trying to move eye muscles in order to get a clear picture. If one slowly pulls back the picture away from the face, while refraining from focusing or rotating eyes, at some point the brain will lock onto a pair of patterns when the distance between them matches the current convergence degree of the two eyeballs.

Spinning tunnels depend upon creating sensory confusion between the kinesthetic system, the vestibular system and the visual system.The body's sense of the motion and the position of the limbs is provided by sensors in the joints, the semicircular canals within the inner ears provide sensory data for the head's position relative to the ground, and the eyes provide input concerning where the ...
Barrier-grid animation or picket-fence animation is an animation effect created by moving a striped transparent overlay across an interlaced image. The barrier-grid technique originated in the late 1890s, overlapping with the development of parallax stereography ( Relièphographie ) for 3D autostereograms .
It consists of 12 lilac (or pink, rose, or magenta), blurred discs arranged in a circle (like the numbers on a clock), around a small black, central cross on a grey background. One of the discs disappears briefly (for about 0.1 seconds), then the next (about 0.125 seconds later), and the next, and so on, in a clockwise direction.
GIF was one of the first two image formats commonly used on Web sites, the other being the black-and-white XBM. [5] In September 1995 Netscape Navigator 2.0 added the ability for animated GIFs to loop. While GIF was developed by CompuServe, it used the Lempel–Ziv–Welch (LZW) lossless data compression algorithm patented by Unisys in 1985.
Mental rotation is the ability to rotate mental representations of two-dimensional and three-dimensional objects as it is related to the visual representation of such rotation within the human mind. [1] There is a relationship between areas of the brain associated with perception and mental rotation.
