The Master of Numbers

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.

Globes within Spirals? (Optical Art Tutorial)

© Gianni A. Sarcone – redbubble.com

Are you seeing spirals? Look again, they’re actually concentric circles! This unique variation of the “Fraser spiral” plays tricks on your eyes by blending a regular line pattern (representing the circle’s circumference) with misaligned elements (the spheres with varying brightness).

Would you like to learn how to create this mesmerizing illusion? Follow my simple visual tutorial. If you have any ideas to further enhance this project, please don’t hesitate to reach out.

“Infinity”, A Kaleidoscope of Squares

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

In these minimalist op art pieces, I delve into the metaphoric realm of geometric shapes, with a particular focus on the hexagon as the foundational element for creating cubes and other simple three-dimensional regular shapes.
The artworks I present depict solid or three-dimensional structures that appear plausible and real, yet are in fact illusions known as ‘impossible figures.’ However, discerning these impossible figures isn’t immediately evident; one must concentrate on specific areas of the representation to grasp that they could never exist in reality! Drawing an impossible stereographic structure becomes achievable by merging two or more contrasting viewpoints or perspectives of the same object, or even by blurring the boundaries between the exterior and interior of an object…
The more ‘normal’ and ‘simple’ an impossible figure appears, the more captivating it becomes! Indeed, impossible objects aren’t created solely to bewilder the eyes; their purpose lies in confounding the mind and challenging one’s acquired visuo-spatial skills and stereographic knowledge.

The two intricate drawings displayed above and below combine two tribars to form an impossible isometric cube, showcasing a mesmerizing interplay between form and illusion.

Op Art Metal Bookmarks

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.

Illusive Color Mixing

When your brain lies… There is NO yellow, nor red, nor green in the picture below! The only real colors are blue, cyan and magenta. Scientists and artists call these color induction effects “simultaneous color contrast” and “color assimilation”.

Concept taken from my book “Drawing Optical Illusions” (2010).

Subliminal Faces

This series of works questions the many cognitive aspects of faces’ recognition. People often see hidden faces in things, clouds, landscapes, or in architectural structures… Finding the latent or virtual image hidden in the manifest image is a mental process related to the concept of the “lost object” used in psychoanalysis. 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.

The Master of Numbers
Collage – mixed media, 2006

Photomosaic portrait of Albert Einstein made with random photographs of numbers.
It is only when the viewer moves away from the image that the portrait of Einstein appears. It is the distance that creates and unveils the truth, because everything is relative as Einstein once said and everything depends on the context, the environment or the point of view.

When Optical Art Meets Illusion

Some simple geometric patterns and designs, when repeated, can induce strong illusory shape distortions. Thus, visual misperceptions are very common in the op art world.

If dark and clear rectangular tiles are arranged in a checkered fashion, as shown below, there is obviously no illusion, but wait, just add at the intersection of these tiles some transparent dark and clear square patches, et voilà, magic appears!

So, transparencies can produce apparent linear distortions. The parallel red lines in this example look like being convergent / divergent.

Op Art On Metal (2)

A visual surprise is hidden within this magical bookmark I created for my partner Art of Play. From one perspective, the grooves in the metal die-cut card seem to be an abstract radial design but place the pattern against a solid dark background and a familiar portrait emerges.

Can you guess who’s this female Mexican artist who once said: “Everything changes, everything moves, everything revolves, everything flies and goes away.”
