Sabato 21 dicembre ti aspettiamo alla Mostra delle Illusioni di Genova per “Paradossal…mente“, il laboratorio interattivo sulla percezione visiva che ho ideato e che guiderò personalmente. Non mancare!
I partecipanti saranno attivamente coinvolti in esperienze che mettono alla prova le percezioni: scopriranno illusioni ottiche inedite, creeranno giochi percettivi sconcertanti e indagheranno vari paradossi e misteri della mente e del sistema visivo. Ogni esperienza invita a riflettere su come il cervello può “ingannarci” o lasciarsi influenzare da ciò che lo circonda
Durata del laboratorio: 1 ora circaIl Materiale per il laboratorio creativo sarà fornito direttamente dalla Mostra delle Illusioni.
Squids are basically the chameleons of the sea, and their secret weapon? Chromatophores—tiny skin cells that let them pull off some mind-blowing color changes. Whether it’s blending into a coral reef or throwing out some serious “back off” vibes, these little guys do it all. Right now, though, this squid seems to be saying: “Hey genius, put me back in the water before you turn me into calamari!”
Chromatophores of the Squid: How Do They Work? Chromatophores are pigment-containing cells found in the skin of squids and other cephalopods. These cells expand and contract to display different colors, allowing the squid to blend into its surroundings, communicate with others, or signal threats. They play a vital role in the squid’s survival.
Here’s the recipe to make an average-sized human: 15 kg of carbon, 4 kg of nitrogen, 1 kg of calcium, half a kg of phosphorus, 200 g of sodium, 150 g of potassium, 150 g of chlorine, a few grams of about 15 other elements (some exotic, like selenium, lithium, and vanadium in trace amounts), and four 10-liter buckets of water.
The 40 liters of water can be made by combining 5 kg of hydrogen and 35 kg of oxygen. Commercial cost? Just a few euros. The hydrogen and a pinch of lithium come from the Big Bang, about 15 billion years ago. The other ingredients are more recent; they required billions of years of cosmic evolution, with stars being born, shining, dying, and reforming in nebulae from stellar collapse. The 15 kg of carbon was formed in a star’s final stages by combining three helium atoms. The 35 kg of oxygen came from the fusion of carbon and helium in extremely hot stars. Iron is the ash of spent stars, and calcium, phosphorus, sulfur, chlorine, sodium, and nitrogen also come from these stellar forges. Traces of even heavier elements reach us from supernovae. In short, we are born from the stars.
In this video, a practical application of topology is presented through a simple knot technique for styling plant pots. This method transforms standard planters into trendy hanging displays.
My op art piece Trinacria (1997) features three black-and-white zig-zagging shapes spiraling together to create the illusion of interwoven concentric circles. These jagged, repeating patterns add a sense of depth to the piece and produce a subtle rotating effect that seems to shift as you follow each line with your eyes.
Prints and canvases of Trinacria are available in my online gallery.
Below, an animated version enhances the effect. By focusing on the center, viewers can observe virtual circles appearing to move inward or outward, adding to the piece’s dynamic sense of rotation and depth.
Ever wondered how Convolutional Neural Networks (CNNs) process images? Imagine putting a photo through a pasta machine… TWICE! This creative experiment, inspired by artist Kensuke Koike, demonstrates how CNNs break down data into smaller, layered features, just like the pasta machine creates four clear images from a single input.
At first glance, they seem to be the same, but take a closer look… Can you spot what’s wrong?
I’ve always been fascinated by impossible figures, which psychologists call “undecidable figures”, meaning visual representations that challenge our perception and understanding of reality. Since the late 1980s, I’ve continued to explore this field and create new illusions, producing a series of drawings that play with the third dimension, manipulating perspectives and proportions to create original visual effects.
My work draws inspiration from two masters of optical art and impossible objects: Josef Albers and Oscar Reutersvärd. Their innovations and creations have always inspired and motivated me to continue my research in this field.
Does the color of wine change when poured into a glass? Although it may appear darker, the red shade remains the same. This visual trick is a result of the Munker-White illusion—where our brain perceives colors differently depending on their surrounding context.

In 1997, I remixed the Leonardo da Vinci’s famous painting Mona Lisa, into 142 perfectly spaced color beads placed at the intersections of an imaginary two-dimensional triangular network. Close up, the picture of the set of beads makes no sense, but if you see it from a distance you will perceive (or at least ‘guess’?) the portrait of Mona Lisa, the most famous Leonardo Da Vinci’s painting.
It is often the little things that are the basis of progress… So let me tell you a little story about the tiniest thing on earth: the dot.
Thousands of years ago, a man in his solitude scanned the night sky and saw all those dots shining like so many still fireflies, and, perhaps for fun, he decided to join them together to form shapes. This is how zodiac signs and astronomy were born.
Far away, in ancient India, the dot symbolized beauty and the eye of knowledge. But even more, the dot they called “shunya-bindu” (शून्यबिन्दु) represented what we nowadays know as zero. It was first a placeholder and then a fully fledged number, for when it is added to the right of the representation of any given digit, the value of the digit is multiplied by ten. This is how our current numbers and decimal numeration system were born.
While drawing or painting, visual artists of all times used to fix a dot – or more specifically a point in space – which was traditionally visualized from the tip of their thumb. Eventually, when this point receded so far away in space, it became known as a “vanishing point”. A vanishing point is where all converging lines of a landscape meet at the horizon. This is how perspective and geometry were born.
One day, medieval musicians were tired of having to rely solely on their memories to remember songs. So they started to use dots, named “puncti”, placed on or between four lines to represent the pitch and duration of a sound. This is how musical notation and programming were born.
In the modern era, at the beginning of the nineteenth century, dots were used in many other symbolic forms: bumps, holes, single tones, flashes of light… Do the terms Braille, Morse, punched card, or pixel sound familiar to you? This is how communication and coding were born.
This is how the humble dot, often overlooked, has served as a fundamental building block for countless advancements throughout history. Never underestimate the power of small things; within a dot was the whole universe.
