It was painters, not scientists, who first figured out the rules of visual perspective and occlusion. Knowing these rules permitted painters to make pigments on a flat canvas appear like a beautiful landscape, rich in depth. Magicians are just a different type of artist. Instead of using color and form, they manipulate the brain’s attention and cognition. (Macknik, Stephen L. PhD and Susana Martinez-Conde PhD. Sleights of Mind. p 4-6.
