Description

The scientific principle behind this game is called retinal persistence. What happens is simple: the images change so quickly that the eyes and the brain do not have time to see each image in turn. The brain still has the first image in mind when the visual information about the second image reaches it. As a result, the brain superimposes the two images to become one.
