Warning: This illusion can make you feel very dizzy, especially if you are prone to motion sickness.
This is one of my favorite illusions because of how intense the motion within the image appears.
No, this image is not animated, the motion is the optical illusion tricking your eyes and brain. The more tired your eyes are the more dramatic the motion will be.
The illusion of motion is caused by the alternating direction of the light or dark highlights on the squares. Many illusions use this technique.
