If you haven’t experienced mind-tripping since those fuzzy days of the 1960s, then prepare for a flashback with eight optical illusions that may leave you feeling a little nauseous and cross-eyed. So, what is a visual illusion exactly? Well, Answers.com says that an optical illusion occurs when “the information gathered by the eye is processed in the brain to give a percept that does not tally with a physical measurement of the stimulus source.” Hmm, that definition could send your head into a spin by itself.
