Ambiguous figures

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.

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.

Triangles of Beauty

Gianni Sarcone

Introducing my latest creation, Triangles of Beauty—a minimalist mosaic that blends geometric precision with visual intrigue. This op art piece showcases a striking arrangement of triangular shapes in sepia tones, merging rich shades of brown and beige. The triangle, a timeless symbol, embodies the balance of masculine and feminine energies, forming a harmonious third element that transcends duality. It represents strength, unity, and the divine—a visual echo of the trinity, where individual components unite into something greater.

Step back and let the patterns unfold to reveal the depth within this thought-provoking piece.

Moona Lisa

Gianni Sarcone

In 1997, I reimagined Leonardo da Vinci’s Mona Lisa through a system of 142 color beads, each precisely positioned at the nodes of an invisible two-dimensional triangular grid. Up close, the pattern appears abstract, yet from a distance, the arrangement resolves into the familiar features of the portrait, inviting viewers to recognize the image through perception and suggestion.

Stereotypes in Visual Perception

Gianni Sarcone


Our unconscious biases and stereotypes can influence our brain’s visual systems, leading us to perceive things and people in ways that align with these stereotypes.

Seeing nude women? Before assuming it’s pornography, reconsider… It’s fascinating how our minds are conditioned and stereotyped: in the first image, we instantly envision women in Adam and Eve attire, whereas the second presents a different reality.

The Master of Numbers

Gianni Sarcone

Presenting “The Master of Numbers,” my acclaimed artwork. This photomosaic portrait, assembled from 288 random number-themed photos, creates a captivating optical illusion, revealing the image of a great physicist from a distance.

Currently showcased in numerous Museum of Illusions globally, posters and prints of this optical art can be found on my online store.

“Infinity”, A Kaleidoscope of Squares

Gianni Sarcone

With this work, I aim to push geometry to its limits, transcending the confines of color. My goal is to showcase the creative potential of simple concentric squares as a medium for experimentation and the discovery of new op art patterns. By delving into this exploration, I strive to unveil captivating illusions of color and mesmerizing motion.


Draw a large and a small square with thick lines and center them (Fig. A). Next, blend the inner and outer squares in six steps to create a set of concentric squares. Reproduce the set to form a larger square pattern, as shown in Fig. B.

“Enigma”, Paradoxical Volumes

Gianni Sarcone

In these minimalist op art works, I explore geometry as metaphor, using the hexagon as a building block for cubes and other regular solids. The forms appear stable and believable, yet they are impossible. Their contradiction isn’t obvious at first; it reveals itself only when the eye slows down and follows the structure closely. By merging incompatible viewpoints and softening the boundary between inside and outside, the drawings turn logic against itself. The more ordinary the form looks, the stronger the effect—these objects are meant less to trick the eye than to unsettle the mind and challenge our sense of space.

Enigma 1: Available as fine prints and t-shirts.

The two drawings displayed above and below combine paired tribars to form an impossible isometric cube, where form and illusion lock into a single structure.

Enigma 3: Available as fine prints and t-shirts.

Here, the “volume” turns itself inside out, quietly echoing the logic of a Klein bottle and unsettling the usual distinction between interior and exterior.

Enigma 2: Available as fine prints and t-shirts.

I am currently in the process of writing an informative book titled “Mastering Optical & Geometric Art: A Journey to Captivating Creations.” With a length of 136 pages, this book serves as an engaging guide to creating visually striking optical art and intricate 2D and 3D patterns. If you are interested in exploring further, I invite you to connect with me on Amazon.

Op Art Metal Bookmarks

Gianni Sarcone

As an artist, I enjoy including subliminal messages or figures in my work. My paintings, photographs and collages play on the foreground and background relationship of our visual perception and represent common or iconic faces the viewer has to rediscover.

In this magical bookmark of my creation, a portrait of M. L. King appears when held over a blank page or up to a light. From his famous words, we are reminded that, “Darkness cannot drive out darkness; only light can do that.” A neat gift available from Art of Play.

While in this one below, a portrait of Gandhi appears when held over a blank page or up to a light — a subtle reminder to read with intention and “Be the change you wish to see in the world.” Still available from my partner Art of Play.
