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 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 illusion, created in 2003 by Japanese web designer Nobuyuki Kayahara, [1] [2] involves the
The Hollow-Face illusion is an optical illusion in which the perception of a concave mask of a face appears as a normal convex face. Hybrid image: A Hybrid image is an optical illusion developed at MIT in which an image can be interpreted in one of two different ways depending on viewing distance. Illusory contours
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.
English: This is a set of spinning disks form the Museum of the university of Coimbra Portugal. They are spinning and the speed creates illusions. They are spinning and the speed creates illusions. Date
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 refers to the phenomenon whereby the three-dimensional structural form of an object can be perceived when the object is ...
Claudet also noted in 1867 that the thaumatrope could create a three-dimensional illusion. A spinning rectangular thaumatrope with the alternating letters of the name "Victoria" on each side, showed the full word with the letters at two different distances from the observer's eye. If the two strings of the thaumatrope are attached to the same ...
The anamorphic disc image (A) and one of the three perceived images when spun (B) as illustrated in Correspondance Mathématique et Physique - Tome VI (1830). During early experiments for his study of physics at the University of Ghent, Plateau looked at two concentric cogwheels rotating in opposite directions, and noted how the fast moving cogs formed the shadowy image of a motionless wheel.
