Where Illusions Begin: Travels, Cultures, and the Art of Seeing

Gianni Sarcone

People often ask me where the ideas for my illusions come from. The truth is, they often arrive quietly, inspired by the places I’ve visited and the cultures I’ve encountered. During my travels, it’s not unusual for me to create something that reflects the spirit of a place. Take “Seal or Bear?” for example—it came to me while wandering through northern Canada, surrounded by the vast, silent landscapes of the Arctic and the rich traditions of Inuit culture. That illusion went on to become a classic in the 1990s and even made its way into textbooks on perception.

Later, during my journey through Japan between Tokyo and Kyoto, I was captivated by the delicate balance of light, shadow, and movement in the world around me. It was there that “How Many Birds?” took shape, in the ukiyo-e style. One of my earliest optical illusions, it explores bistable perception in a playful way. Depending on your gaze, you can see four birds nestled in their respective nests with one perched on a branch—or four chirping chicks gathered around their mother. I like to think that, in that moment, the spirit of the place and the quiet rhythm of daily life found a way into the lines and spaces of the image, letting viewers glimpse more than one reality at once.

Ultimately, I am like a sponge, absorbing everything that orbits around me, all while staying true to my own style. That is simply how I work.

Latest Update

The NHK Educational Corporation, a production subsidiary of Japan’s public broadcaster NHK responsible for a wide range of educational programming, will feature the “Seal or Bear?” illusion in 2026 and 2027 as part of a series on psychology education and visual perception.

The Human Condition: A Paradox

Gianni Sarcone

What strikes in the tiny space between God’s and Adam’s fingers in the Sistine Chapel is neither mysticism nor religion—it is humanity itself. Michelangelo, perhaps without realizing it, captures a simple yet profound truth: the hardest distance to cross does not depend on strength or span, but on “human will”—or its absence.

We perceive a tension in the image: God leans forward, taut and ready to give all He can. Adam, by contrast, extends his hand half-heartedly, hesitant, the finger limp and weak. That missing centimeter seems, at first glance, to symbolize free will—or the refusal of determinism: the choice to make a tiny gesture that can shift our understanding of life, to move forward with conviction, or to remain still, waiting for everything to arrive on its own.

The fresco speaks beyond faith: to moments when we could act, yet remain still. Stillness is not failure—it is awareness. Like Wu Wei (無為) in Zen philosophy, it is effortless action: a letting go, a recognition that life flows even when we do not grasp it. Free will and determinism fade into labels, defined only by belief.

That one-centimeter gulf becomes infinite. It stretches across light-years, embodying the human condition: our extraordinary capacity to feel and aspire, in tension with the world, facing life’s trials and the inevitability of our own mortality.

Invent Monopoly—Don’t Collect $200…

Gianni Sarcone

Few stories of creative and intellectual theft are as striking—or ironic—as the origins of the billion-dollar phenomenon known as Monopoly. It all began with Elizabeth “Lizzie” Magie, a brilliant economist and game designer, who in 1904 created The Landlord’s Game to illustrate the dangers of property monopolies and rent-seeking. Her game included two rule sets: one showing how wealth concentrates under monopolies, and another promoting shared prosperity—a subtle critique of unrestrained capitalism.

Over the decades, her game spread informally, with players adapting it to local streets and rules. In the early 1930s, Charles B. Darrow encountered a variant, tweaked it, and sold it as Monopoly. Parker Brothers bought the rights in 1935, marketed it as Darrow’s invention, and turned it into the family-friendly capitalist pastime we know today—while Magie received a mere $500 for her patent and vanished from the mainstream narrative.

The irony is bitter: a game designed to expose the dangers of monopolies became one of the most lucrative symbols of them. And the woman who invented it? Forgotten, while the world continues to pass “Go” and collect $200.

What If the Late Middle Ages Hit ‘Delete’?

Gianni Sarcone

I often catch myself wondering how different our art, our literature, our techniques, our architecture, our science, and all our so-called achievements would be if, at some point in history—say, right after the late Middle Ages—everything humanity had created were wiped out so thoroughly that no one could even recall what a wheel looked like. A world where no one knew whether the Venus de Milo had been a place, a painting, a wine, a poem, or perhaps an ancient weapon. And where “democracy” or “monarchy” might just as well be fireworks or seasonal mushrooms.

As for me, I suspect that the evolution of such a world would feel strangely familiar while being completely different, a kind of cosmic déjà vu. Everything reinvented, yet uncannily the same. Worn-out ideas would return with fresh paint, old opinions would resurface disguised as revelations, eccentric religions would bloom—new in appearance, ancient in essence—and intolerance would simply find new masks. I don’t imagine this world as a better one. No, not that… just the same stage with new props, perhaps a bit more entertaining.

After all, when the dinosaurs vanished in an instant, life went on—and brought forth creatures no less terrifying. Take humans, for example.

But what do you think?

Old New World

Punctum Temporis

Gianni Sarcone

What is an instant—the punctum temporis—that Plato called ἐξαίφνης (exaíphnēs), the sudden? Is it a vanishing point between past and future, or the hinge on which both unfold? Plato saw it as an interruption in the flow of time, a fleeting spark where change occurs, yet which itself seems to escape duration. Augustine later reflected that the present, though indivisible, lives within us as the tension between memory and expectation.

Bergson went further, arguing that real time—la durée—cannot be reduced to a series of measurable instants. If an instant is infinitely small, it cannot be summed; if it can be summed, it is no longer an instant. Thus arises the paradox: if the present is composed of infinite instants, how can it ever be said to exist?

Perhaps time is not made of points but of relations—of movement, perception, and becoming. The instant would then be less a unit of time than a threshold of consciousness, the meeting place of continuity and change. In that sense, punctum temporis is where time reveals its true nature: elusive, dynamic, and inseparable from the act of being.

Ananke’s Die

Gianni Sarcone

A simple study in visual perception—an exploration of how a plain hexagon can evolve into the illusion of a cube. Through precise geometry and controlled form blending, static lines awaken into rhythm and volume, giving rise to a subtle sense of depth and movement.

Constructing the Illusion

Fig. A — The Base Shape
Start with a regular hexagon. Divide it into three equal diamond shapes (rhombuses)—these represent the three visible faces of the cube. Each diamond has four equal sides: two acute angles (60°) and two obtuse angles (120°). Together, they form the geometric foundation of the cube.

Fig. B — Building Volume with Shape Blends
In Illustrator, or any other vector software, use the Blend Tool to create a shape blend inside each diamond. Start with a small central circle and blend it toward the outer edge of the diamond. Adjust the number of blend steps to control how smooth or tight the transition appears. This process builds the cube’s apparent volume and visual tension. You’ll notice that the distance from corner to corner in the nested, diamond-like shapes is slightly greater than from side to side, creating subtle gaps that lead the eye to perceive an X across the surface.

Fig. C — Perspective and Transformation
Distort slightly the hexagon to set the three diamonds in perspective. This step transforms the flat figure into a die-like cube, giving it spatial depth and presence.

Enhancing the Optical Effect
Next, add horizontal background lines and some color, as shown in the two examples in the image. You can also adjust the illusion by making the visible faces of the die appear slightly concave, as in the figure on the right. This effect is created by shifting the concentric, nested diamond shapes slightly off-center—the position of the central ellipse determines whether the die appears concave or convex.

Below is the finished stage of the work. Curiously, the cube appears to hover, slide, and even emit a faint blue glow—though it remains entirely black and motionless.
Ananke’s Die is a study I began in 2010, a continuing exploration of how repetitive lines and geometric precision can trick the mind into sensing motion and color where none exist.

Why Ananke’s Die

I titled this work Ananke’s Die after Ananke, the Greek goddess of necessity and fate.
The cube, a symbol of structure, represents order and control. Yet the three visible faces that seem to define its volume are an illusion—shifting and unstable.
Under the viewer’s gaze, the shape changes, its meaning shifts, yet the form remains.
This illusory die shows the balance between order, perception, and destiny, reminding us that what we think we control often exists within the unpredictable interplay of vision and inevitability.

This image also triggers multiple associations in a loop: hexagon, cube, die, chance, illusion, order, fate, contradiction. These connections show how perception mixes stability and randomness, revealing that what we see is shaped as much by the mind as by reality.

Forbidden Brews: When Coffee, and Chocolate Stirred Trouble

Gianni Sarcone

In the 17th century, some of today’s most beloved drinks — coffee, tea, and chocolate — were once viewed with deep suspicion. When these “divine beverages” first arrived in Europe, civil and religious authorities saw them as exotic, even subversive. Their foreign origins and stimulating effects made them objects of fascination, controversy, and at times, prohibition.

Coffee traces its roots to the highlands of Ethiopia, where the Coffea arabica plant produces the precious beans that, once roasted and brewed, yield the dark, fragrant drink we know today. From Ethiopia, coffee spread to Yemen and across the Islamic world before reaching Europe. In 1672, an Armenian merchant named Pascal introduced the first coffee to Paris, setting up a small stand near the Saint-Germain fair — an event that marked the beginning of France’s enduring love affair with the drink.

Chocolate has an equally captivating story. It comes from the seeds of the Theobroma cacao tree, native to Central and South America. The Maya and Aztec peoples prepared it as a sacred, bitter beverage, often mixed with spices and chili — a divine elixir meant to awaken both body and spirit.

These exotic drinks, however, sparked strong reactions. Coffeehouses became lively meeting places where new ideas brewed alongside cups of steaming coffee — much to the concern of kings and clergy. Chocolate, too, stirred debate within the Church: some saw it as sinful indulgence, others as a heavenly pleasure.

Even in the Age of Enlightenment, the story continued to brew with conflict. In 1777, Frederick the Great of Prussia tried to ban coffee altogether. He feared it would replace beer — the national drink and a source of tax revenue — and even claimed that beer made his soldiers strong, while coffee made them weak. To enforce his will, he appointed “coffee sniffers” (see picture) to hunt down those secretly roasting beans.

Despite resistance and regulation, these once-suspect beverages soon became powerful symbols of refinement, curiosity, and creative thought. Today, coffee, tea, and chocolate remain faithful companions of conversation, reflection, and imagination.

A Personal Reflection: Forbidden Pleasures and Creative Sparks

This history of suspicion and fascination mirrors the journey of modern art. Like coffee, tea, and chocolate, art has often been feared, censored, or condemned. Impressionists were mocked for daring brushstrokes; avant-garde movements were branded degenerate under totalitarian regimes. But prohibition, ridicule, or misunderstanding never extinguished their appeal — instead, it made them irresistible.

I see in these stories a reflection of human curiosity itself: the desire to taste, to see, to explore what lies beyond the accepted, the safe, the ordinary.

The Responsive Eye

Gianni Sarcone

“The Responsive Eye,” held at MoMA in 1965 and organized by William C. Seitz, was a landmark exhibition in Op Art. Featuring over 100 artists—including Bridget Riley, Victor Vasarely, Richard Anuszkiewicz, and Josef Albers—it explored how geometric patterns and color could manipulate perception.

Riley stood out with her precise, rhythmic paintings that seemed to move and breathe, challenging the way we see. The show fascinated the public, drawing huge crowds, and sparked a wave of interest in optical effects across art, design, and fashion.

Critics were divided. Some celebrated its innovation and playful engagement with vision; others dismissed it as flashy spectacle, questioning the depth and seriousness of Op Art. Personally, I see it as a pivotal moment—one that reminded everyone that perception itself could be the medium, and that art could be both cerebral and exhilarating.

Small Strokes, Big Meanings

Gianni Sarcone

Human writing systems are built from strokes. I’ve always been fascinated by how a simple line or mark can alter the sound or meaning of a letter, pictogram, ideogram, hieroglyph, or sinogram. Exploring scripts across the world—even from countries far apart—revealed surprising connections, almost like hidden equivalences between them. The true marvel is how our eyes can sense meaning, even when tiny, seemingly insignificant changes are made to the original sign.

In some writing systems—especially those built on characters rather than alphabets—a subtle visual change can completely shift meaning, much like how English plays with homonyms and homographs. But here, it is the visual structure itself that carries the transformation.

Take the Chinese character 人, meaning “person.” In Chinese and Japanese, this simple shape often acts as a base or radical. By adding a stroke, adjusting placement, or combining it with another element, you get entirely new words and concepts. A single alteration can lead to a dramatic change in meaning.

Here are a few examples showing how characters evolve from that shared visual root:

  • 大 (dai, oo) — “big, large”
    Looks like a person with arms extended. One stroke changes the meaning from “person” to “large.”
  • 太 (tai, futo) — “fat, thick”
    Add a small dot below 大, and the concept shifts from “big” to “overly big” or “thick.”
  • 犬 (ken, inu) — “dog”
    A short slanted stroke above the horizontal line of 大 turns the human figure into an animal.
  • 天 (ten, ama) — “heaven, sky”
    By placing a stroke above the “big” shape, the idea rises upward—symbolically to the sky.
  • 矢 (shi, ya) — “arrow”
    Adding a vertical stroke that meets the upper horizontal line of 天 turns it into a tool or weapon.
  • 火 (ka, hi) — “fire”
    Here the strokes branch downward, evoking sparks or flames.
  • 炎 (en, honoo) — “flame”
    Double the fire element and you intensify the meaning: from fire to blazing flame.
radical transformations

What’s striking is how these changes don’t require entirely new symbols—just minimal visual tweaks. Where English relies on spelling or pronunciation shifts (like lead the metal vs. lead as in to guide), character-based languages often rely on visual logic. A dot, a stroke, or a slight rearrangement can redirect the meaning toward something bigger, higher, brighter, or more intense.

It’s a compact, elegant way to build vocabulary: meaning evolves visibly, not phonetically.
