Hypnotic Disc

Gianni Sarcone

Take a moment to focus on the circular pattern. How many spirals do you see? The surprising answer is none. There are no spirals here—just alternating black and yellow discs, slightly off-center and layered to create a striking illusion of swirling depth and motion.

I began crafting pieces like this in the early ’90s, drawing inspiration from Duchamp’s Rotoreliefs. I was captivated by how simple rotation could deceive the eye, inviting the viewer into a world of optical illusions. It’s a unique experience—seeing motion and depth in something entirely flat, both puzzling and mesmerizing.

This op art pattern comes to life across various mediums and transforms into artistic expressions on different objects. In my online gallery, you’ll find art prints and everyday items featuring this work, all available for purchase.

Gliding Patterns: The Anomalous Motion Illusion

Gianni Sarcone

Let your gaze wander across the image below. Do the shapes in the first and third rows seem to subtly shift leftward, while the second and fourth rows appear to glide rightward?

Now, let your gaze wander across the image below. Do the concentric circles appear to subtly counter-rotate?

Why do these static images appear to move? This perceptual phenomenon, known as “anomalous motion” or “peripheral drift illusion”, results from the interplay of color contrast, luminance, and eye movements. It occurs due to a sawtooth luminance grating in the visual periphery, where a sequence of contrasting colors transitions from light to dark. The speed of the perceived motion is influenced by the frequency of microsaccadic eye movements.

In the 1990s, I began creating many of these fascinating images, experimenting with patterns and contrasts to bring this mesmerizing effect to life.

Fine art prints and merchandise of these mesmerizing pieces are available in my online gallery—a perfect addition to any space!

Perspective Optical Illusions: The art of circling the square

Gianni Sarcone

When bending the sides of a square structure forward, each edge forming a sine wave shape, the structure reveals a circle when viewed from the reverse angle. This illusion plays with perspective, specifically utilizing an effect known as “anamorphosis“.

Anamorphosis refers to a artistic technique that uses perspective to create distorted images that can only be viewed correctly from a specific angle.

Duality in Motion

Gianni Sarcone

Explore a fascinating figure/ground effect in this op art piece, where 4 black illusive bangles appear to overlap with 4 white ones. The rotating patterns create a calming and hypnotic visual experience.

This design is now available as t-shirts and posters in my online gallery.

If you’re interested in creating your own op art, I also have a tutorial available on Behance.

I hope you enjoy this design, and I’d love to hear your thoughts on it!

KINECHROMATICS: A new three-framed animation

Gianni Sarcone

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.
