Is this a real perpetual motion machine?
Obviously not… The closest thing to a “perpetual motion machine” is the Beverly clock whose mechanism is driven by variations in atmospheric pressure, and by daily temperature variations.

This is one of my earliest color optical illusions. There is no yellow or green in the diamond shapes, just vertical black lines! (If you don’t believe it, use a eyedropper tool to check it.) This intriguing visual effect is mainly due to “simultaneous color contrast induction“.

“Deep Blue”, the yellowish rays you see in this picture are a construct of your brain. My op art work is available as prints from Saatchi Art gallery.

Salvador Dalí : Sept corps nus et un crâne, 1951 (Human skull consisting of seven naked women).

Often symbols of MORTALITY (or some romantic notion of immortality – as the belief that a spiritual part of a person survives death) and POWER, skulls have been employed in human rituals and art since the dawn of humanity: from the ancient animal skulls in Paleolithic burial sites, to the curlicued cattle skulls that haunt Georgia O’Keeffe’s canvasses. Skulls cannot be assumed to be only a mere symbol of death, they are also used in initiation rituals as a symbol of REBIRTH, symbolizing the ‘sephirah daath’ (סְפִירָה – sephirah, “enumeration” in Hebrew) on the cabalistic tree of life, the gateway to a higher awareness only achievable through spiritual death and rebirth.
For over 10 years, I’ve had the pleasure of collaborating with Focus, an Italian monthly popular science magazine published in Milan.
In October 2020, Focus released issue #336, which featured my article and optical illusions. This special edition included a 10-page dossier on visual perception, showcasing over 13 original illusions I created, complete with explanations.
The cover of this issue also featured a unique effect I designed for Focus. As you read the main title, the cover image moves, and, intriguingly, the title changes depending on your perspective—read closely, and it says ILLUSIONI; look from a distance, and it transforms into COSA VEDI?

My autokinetic optic art will be presented and discussed in the German fashion magazine “Barbara” to be released on July 8.

Here is a neat optical illusion project I was commissioned by “Art of Play“. From one perspective, the grooves in the metal die-cut bookmark seem to be an abstract design but place the pattern against a solid background and a familiar figure pops into view!

Here are two projects involving the geometrical-constructive art of Piet Mondrian, one of my preferred artists, the golden ratio and ϕ. For this purpose, I used the same color palette favored by Mondrian: yellow, red, blue, black and gray.
In the first project, I used squares, that are proportional to each other by the golden ratio or ϕ, to prove the Pythagorean theorem as shown in the Zhoubi Suanjing (or Chou Pei Suan Ching – 周髀算經), one of the oldest Chinese mathematical texts (circa b.c. 200).
“Bathers”, incredible etchings by Swedish artist Anders Zorn (1860-1920). Zorn pursued light as the guiding principle of his art. The expression of light on the human form and his beloved homeland was the foundation of his work, and drove him with an intensity visible in the details from his multiple etchings.
