A nifty little parallax and perspective demo by University of Hertfordshire Professor of the Public Understanding of Psychology, Dr Richard ‘Quirkology’ Wiseman.

The effect: three terrain vehicles below appear different in size because of the surrounding environment. This is because of depth perception our brain automatically processes. Now take something to measure them, and you’ll realize they are exactly the same.

Back in 2007, this image was voted Optical Illusion of The Year by the Neural Corelate Society:
These images of the Leaning Tower are actually identical, but the tower on the right looks more lopsided because the human visual system treats the two images as one scene. Our brains have learned that two tall objects in our view will usually rise at the same angle but converge toward the top—think of standing at the base of neighboring skyscrapers. Because these towers are parallel, they do not converge, so the visual system thinks they must be rising at different angles.
