Look at the picture from a certain distance and check which colors are in the patchwork.

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!

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?

My recent work “The Master of Numbers” is a photomosaic portrait of Albert Einstein made with random numbers. Can you guess how many times does the number 42 appear in the picture?
It is currently exhibited in many Museum of Illusions all around the world. Posters and prints of this optical art are available from my online store.
