Favorite Optical Illusions

If you look at the image as a whole, it appears the circles are moving. But if you focus on one circle or two adjacent ones, they don't seem to move. The illusion seems to be triggered by saccadic eye motions. Saccades are rapid eye movements used in repositioning the fovea to a new location in the visual environment. They are both voluntary and reflexive. A fovea is a region of the retina where the concentration of rods and cones is the highest and therefore vision is the sharpest. Thanks to Merlin Jetton for this explanation.
