KINECHROMATICS: A new three-framed animation

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’…Kinechromatics static image Continue Reading

Dynamic Müller-Lyer Illusion

Prize illusion sarcone

I am very proud that my “Dynamic Müller-Lyer Illusion” won the third prize as best illusion of the year 2017!

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.

Super Optical Illusions

The outside world is mediated through our sense organs, so what we perceive and feel are just representations of reality. The only things we cannot doubt are our inner emotions: we cannot doubt that we are happy, sad, in love, or in grief, when such states apply. The only other thing we cannot doubt is… to doubt!

Super Optical Illusions (aka Xtreme Illusions 2) is a children book project I enjoyed to make three years ago for the publishers “Carlton Books” [], “National Geographic Kids” [] and “Ça m’intéresse” []. 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).

Reuleaux-triangle intermittent mechanisms

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…

Flying Gothic Bat

A new kinoptic design taken from my book “Extreme Illusions 2”.

Kinoptic designs are optical illusions where a static image appears to be moving due to the cognitive effects of interacting color contrasts and shape position. The essence of Kinoptic Art is actually to play with our optic nerves, to surprise and create the illusion of colors, dimensions or motion. Op Artist uses a palette of elements like blank spaces, XOR spaces, interspaces, interferences, space tiling and geometric patterns. Precision is also important in my creative processes: a small change in an Kinoptic Art picture can strongly modify or negate a visual effect.

The bat in the picture below seems to flutter, move and/or expand. Moreover, if you stare for a while at it and close your eyes, you will see a smaller white bat appearing to be painted on the insides of your closed eye lids.
