A visual puzzle. On a white surface, dark blue squares dance in front of the observer.
It is almost impossible to fix the eye and the mind is becoming confused because these are just dark blue squares in different positions and perfectly aligned. What is happening? What you are looking at? Are you sure?
This picture asks questions. A classical, intriguing, alluring Op Art image.
To maintain the optical illusion effect the size of this picture has to be at least 60 cms squares and other colours can be used for the flying squares.
