[Set of photos] Lie to you without discussion: Dynamic illusion in Op art

Most hallucinatory graphics are not invented by scientists, they are the work of visual artists. These artists aim to create visual illusions in their artworks by gaining insight into how the visual system works. Long before the advent of visual science as a formal discipline, painters had devised ways to trick our brains into thinking that flat canvas was three-dimensional, and then skillfully trick us into thinking that the still life in front of us was a plate of luscious fruit. The visual arts are often ahead of the visual sciences in discovering the basic principles of vision, using a systematic research approach (though largely relying on intuition). In this sense, art, illusion and the science of vision are, in fact, often interlinked.
