# Best Illusion of the Year Contest

The Best Illusion of the Year Contest is an annual recognition of the world's illusion creators awarded by the Neural Correlate Society. The contest was created in 2005 by professors Susana Martinez-Conde and Stephen Macknik as part of the European conference on Visual Perception in La Coruna, Spain. It has since transitioned to an online contest where everyone in the world is invited to submit illusions and vote for the winner.
The contest decides on the most impressive perceptual or cognitive illusion of the year (unpublished, or published no earlier than the year prior to the most recent competition). An illusion is a perceptual or cognitive experience that does not match the physical reality (e.g. the perception of motion where no such motion physically exists).
As human experience is generated indirectly by brain mechanisms that interact with the physical reality, the study of illusions offers insight into the neural bases of perception and cognition. The community includes neuroscientists, ophthalmologists, neurologists, and visual artists that create illusions to help discover the neural underpinnings of illusory perception.
The Best Illusion of the Year Contest consists of three stages: submission, initial review, and voting of winners. The initial review is conducted by a panel of judges who are world experts in the science, art, and science education. The judge panel narrows the submissions to the Top Ten finalists, and viewers from all over the world can vote for the winner online. The top three winners receive cash awards.
