Although NOTHING moves on the gif below – only the colors change! – it’s easy to spot which direction the wheel is “rotating”… But which side is in front? Which side the back?
Another hypnotic version in which still squares and diamonds seem to move, but only colors change slightly!
Is this a real perpetual motion machine?
Obviously not… The closest thing to a “perpetual motion machine” is the Beverly clock whose mechanism is driven by variations in atmospheric pressure, and by daily temperature variations.
My autokinetic optic art will be presented and discussed in the German fashion magazine “Barbara” to be released on July 8.
Which direction is the rotation? Some spokes appear to rotate CW while the disc rotates CCW.

I would like to present a new way of my invention to animate static images with the interaction of additive and subtractive colors. I have called this new animation system KINECHROMATICS (patent pending).
The static image below is made of 3 layers having each a different subtractive primary color (magenta, yellow, or cyan) blended in ‘multiply mode’…

As you surely know, the “BEST ILLUSION OF THE YEAR CONTEST” is a yearly competition under the patronage of Scientific American, organized by the Neural Correlate Company (New York, USA).
Müller-Lyer’s illusion proves that a segment can visually appear longer or shorter depending on the sense of the arrow heads at its ends. In what consists my variant? As shown in the animation, the red dot in the middle of the line is equidistant from the other two red dots, although the ends of the line visually appear to alternately stretch and shrink like a rubber band!
The radial version of the illusion is even more impressive:
The perceptual increasing and decreasing of the segments occurs in a very short time. Thus, I suppose it is more a physiological phenomenon, rather than a psychological bias. Our attention seems to be attracted by the receptive field WITHIN the V-shaped arrow heads, causing an illusory inward or outward shift of the ends of the line.
From the static image shown below (representing an automated conveyor system), it is possible to create a looping seamless animation…
Super Optical Illusions (aka Xtreme Illusions 2) is a children book project I enjoyed to make three years ago for the publishers “Carlton Books” [amazon.co.uk], “National Geographic Kids” [amazon.com] and “Ça m’intéresse” [amazon.fr]. It looks really fantastic and my pictures are large to enjoy the details! It is a family book that will encourage the young reader to explore the mysteries that lie right inside our own minds (including the key scientific concepts of perspective and perception).
Book Cover
The Reuleaux triangle is a convex triangle-like shape, each side of which is an arc centered on the opposite vertex. Any curve of constant width can form a rotor within a square, a shape that can perform a complete rotation while staying within the square and at all times touching all four sides of the square.
Intermittent motion mechanisms were first used in sewing machines, nowadays they are used in many mechanical applications to index film in cameras, projectors, and in film processing equipment…
Klein quartic has 24 symmetries forming a group isomorphic to the rotation/reflection symmetry group of a tetrahedron. Algebraically speaking, this group is S4: the permutations of 4 things.
