“Unspirals” is a series of silkscreen-print projects (still in progress). These colorful geometric op art works appear to rotate and move. They are great promotional supports for companies and products.

Illusive Halo
An optical illusion I created years ago for the Gewerbemuseum of Winterthur, Switzerland. The orange halo around the contour of the eye doesn’t exist, it’s a construct of your brain.
This illusive effect is related to the “neon color spreading” phenomenon.
Amazing Brightness Constancy Effect
Look carefully at the saw-tooth wave patterns on this picture. Is the background of the picture uniformly gray or are there different shades of gray?
Brightness constancy makes some vertical strips look darker, when in fact the gray background is all the same shade of gray.
This op art work is available as prints and canvases from my official online Gallery.
Turning Gray Shades Into Colors With A Tinted Geometric Grid
This is an old technique that uses the “color assimilation” effect to colorize pictures. This perceptual effect, also known by scientists as the Von Bezold spreading effect, occurs when our visual system transfers perceived colors to their adjacent areas.
Is the first photo of a variety of pumpkins in color?
Ghost Colors
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“.
Illusive Color Radial Beams
“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.
Color Luminance Sensibility
Do the light gray triangular shapes in the diagram below have the same hue and brightness?
Illusion of Color
Look at the colored rings from a distance. Then decide which ones have YELLOW inner circles, and which ones have BLUE inner circles.
Is Magenta a Real Color?
Most of us are familiar with magenta — it’s a kind of purplish-red that exists between blue and red on color wheels (color wheels don’t accurately represent the physics of photons, but they represent the philosophical reality: color is a human construct that helps us interpret wavelengths to better understand our world).
The odd thing about color vision is that magenta (or pink) color is not in the spectrum of colors, meaning it cannot be generated by a single wavelength of light. Our brains interpret the color sensation of magenta/pink as ‘absence’ of green.

Autokinetic Wireframe Cubes
Curiously enough, the cubes don’t move only the background color changes…
Here is my tutorial to create an amazing autokinetic animation.
