THIS stunning optical illusion can make users dizzy if they look at it for too long.
Called the Pinna Entwined Illusion, the image was created by Baingio Pinna of the University of Sassari in Italy.

What is the Pinna Interlocking Illusion?
In Pinna’s optical illusion, users can see various circles made of smaller yellow and black squares.
When looking at the image, the circles appear to spiral across each other.
But in reality, they are an ordered set of circles that don’t touch at all.
What happens to this illusion?
Like many others, this illusion works by using colors and shapes to fool the human mind.
Placing squares, which change color from one circle to another, creates a contrast that makes your brain think they intersect.
It also creates an illusory motion effect that makes your mind feel like the circles are spinning.
An expert in optical illusions explains: “The scale and spacing of the squares are just right to achieve that alignment, and as a result, the effect is enhanced by the inward-turning and spiraling effect due to the orientation of the squares. “.
“The edges combine to give an effect like disturbing waves. The illusion appears to be a fuzzy process that is often remarkably effective at filtering out key information about the edges and their orientation in the field of view.”
“To a much greater extent than we realize, we infer global configurations from what we see only in the central and foveal region of the visual field. This also seems to be the case with impossible three-dimensional shapes.”
Other similar illusions include those of Akiyoshi Kitaoka, a professor of psychology in Kyoto, Japan.
One of his most famous illusions, the spinning snakes, consists of circular snakes that appear to spin spontaneously in your peripheral vision.

However, when you focus on a circle, the rotation seems to stop.
This is likely caused by unconscious rapid eye movements and blinking, The Guardian writes.
