Even bounded, my dynamic Müller-Lyer illusion works perfectly; the static segments of the star appear to alternately contract and expand.

Illusive Moving Wheel
Although NOTHING moves on the gif below – only the colors change! – it’s easy to spot which direction the wheel is “rotating”… But which side is in front? Which side the back?
Another hypnotic version in which still squares and diamonds seem to move, but only colors change slightly!
Math-Magic Vanishing Space
Inspired from the astrological tables, here is a new puzzle of my creation designed according to the ‘Golden Number Rules’, which is reflected in the proportion of each single piece of the game. Thanks to the balanced dimensions of its pieces, this puzzle acquires some intriguing magical properties!
This “math-magical” puzzle is composed of a tray in which the pieces are assembled.

Apparitions
This ghostly face appears to mysteriously change its features when you look at it for a while (Some viewers have even reported experiencing traumatic visions!). But that’s not all – if you unfocus your eyes and look steadily through the image, you’ll notice that after about 10-15 seconds, the face gradually disappears…
This spooky portrait is created by merging together 50 common human faces. The process of averaging multiple exposures of human faces isn’t really new. In fact, as early as 1879, Sir Frances Galton experimented with this photographic technique, and others have since followed suit, using it for artistic or social purposes. Artists like Ken Kitano, Jason Salavon, Donald Scott Bray have all borrowed this technique for their own work.

Perpetual Motion
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.
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“.

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.
Magic Tic-Tac-Toe
Our visual system can interpret colors and shades in surprising ways. With this 3×3 Tic-Tac-Toe grid I would like to show that our sensibility to color brightness can be easily fooled. Well, do you notice something particular in the grid below?
