An illusion is a distortion of the senses, revealing how the brain normally organizes and interprets sensory stimulation. While illusions distort reality, they are generally shared by most people. Illusions may occur with more of the human senses than vision, but visual illusions, optical illusions, are the most well known and understood. The emphasis on visual illusions occurs because vision often dominates the other senses. For example, individuals watching a ventriloquist will perceive the voice is coming from the dummy since they are able to see the dummy mouth the words. Some illusions are based on general assumptions the brain makes during perception. These assumptions are made using organizational principles, like Gestalt, an individual's ability of depth perception and motion perception, and perceptual constancy. Other illusions occur because of biological sensory structures within the human body or conditions outside of the body within one’s physical environment.

Great app. Those of you with black screens have three things. No patience, bad eyesight, and a ruined iPad. You have one of them. Omg. Don't give the app a bad*** review if your device is broken.
Fun but incomplete
I've always liked optical illusions and this app has a number. But no explanations or any details. I've seen a bunch of these before but I'd like to see more accompanying information.
Glad it was free..
