I really enjoy communicate the mysteries behind the science of perception in a simple and clear manner with the use of instructive images.
We live in a “reallusive” world… Illusions are not totally unreal, because we feel them as they were real. Reality is also a kind of ‘illusion’. The outside world is mediated through our sense organs: vision, hearing, taste, touch and smell. All what we perceive and feel are just REPRESENTATIONS of reality, not the reality itself.
Children have a different way of looking at the world. So, writing and illustrating optical illusion books for kids is not an easy task, because they are less fooled by visual illusions than adults. This is due to the fact that brain’s capacity to consider the CONTEXT of visual scenes, and not just focus on SINGLE PARTS of scenes, develops very slowly.
My new work “Optical Illusions” will make you question: “is seeing believing?”… The brain is an amazing thing, but it doesn’t always get things right when it comes to sight. My book is here to explain why, with astounding images, baffling puzzles, and simple reveals. Continue Reading
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).
An op art sculpture and/or a fidget puzzle to play with over and over!
“Dynacube” is a new line of 3D puzzles featuring my optical art. It isn’t just a puzzle but also a living piece of art. This 3D game is available in 4 distinct styles from Recent Toys: http://www.recenttoys.com/project/dynacube/
Dynacube is a fun game for kids and adults alike to practice their logical thinking and motor skills.

This is one of my earliest self-moving op art work (2003). Have a look at the static image above, don’t you have the feeling that the sets of lenticular shapes seem to expand? Continue Reading
I am working on a new two-dimensional variant of the Müller-Lyer illusion… You may be surprised to know that the Müller-Lyer illusion isn’t only linear: it involves plane geometry too! In fig. A shown below, the ends of the blue and red collinear segments, arranged in a radial fashion around a central point, delimit two perfectly concentric circles. However, for most observers, they seem instead to define a large ovoid that circumscribes another one, slightly eccentric (Fig. B). This comes from the fact that the red segments seem to stretch towards the lower part of the figure, while the blue segments seem to stretch towards the upper part of the same. As you can see, in this variant comes also into play the “neon color spreading” effect. In fact, a bluish inner oval-like shape appears within the black arrow heads (Fig. A), though the background is uniformly white.
Bamboozle your mind with Super Optical Illusions – my book of brain boggling artworks is a clever gift for curious-minded children. Find hearts that beat in the middle of the page and snail shells that spiral off into infinity. Enjoy a preview of my eye popping illustrations below and look for many more in Super Optical Illusions – available now!
As an author, designer, and researcher in the field of visual perception and creative thinking, I like to combine art, psychology, cognitive sciences, and recreational logic to test people’s ingenuity.
I have created or adapted most of the illusions contained in my books. Many were created and perfected during my workshops which are held for the benefit of children and adults alike (more information at: http://www.archimedes-lab.org/prospatelier.html).
Try to solve the optical illusion puzzles below without looking at the answers.
After the success of my book “Drawing Optical Illusions“, I was commissioned by Imagine Publishing for a new tutorial book project titled “How To Draw Incredible Optical Illusions” [You can get this book from Amazon US and Amazon UK]
My book dissects the most fascinating and confounding black and white optical illusions, patterns and tiling, explaining in a concise fashion how they work, how to design and create them, and how to personalize and play with them to your heart’s content. With accessible yet fascinating text and workable samples, this intriguing art ‘cookbook’ is appropriate for graphic designers, teachers, artists, art lovers and the curious who enjoys contemplating how the mind works and how the eye sees.

The outside world is mediated through our sense organs, so what we perceive and feel are just representations of reality. The only things we cannot doubt are our inner emotions: we cannot doubt that we are happy, sad, in love, or in grief, when such states apply. The only other thing we cannot doubt is… to doubt!
Super Optical Illusions (aka Xtreme Illusions 2) is a children book project I enjoyed to make three years ago for the publishers “Carlton Books” [amazon.co.uk], “National Geographic Kids” [amazon.com] and “Ça m’intéresse” [amazon.fr]. It looks really fantastic and my pictures are large to enjoy the details! It is a family book that will encourage the young reader to explore the mysteries that lie right inside our own minds (including the key scientific concepts of perspective and perception).
A new kinoptic design taken from my book “Extreme Illusions 2”.
Kinoptic designs are optical illusions where a static image appears to be moving due to the cognitive effects of interacting color contrasts and shape position. The essence of Kinoptic Art is actually to play with our optic nerves, to surprise and create the illusion of colors, dimensions or motion. Op Artist uses a palette of elements like blank spaces, XOR spaces, interspaces, interferences, space tiling and geometric patterns. Precision is also important in my creative processes: a small change in an Kinoptic Art picture can strongly modify or negate a visual effect.
The bat in the picture below seems to flutter, move and/or expand. Moreover, if you stare for a while at it and close your eyes, you will see a smaller white bat appearing to be painted on the insides of your closed eye lids.
You can see more samples of my kinetic optical art on Smithsonian Magazine.
