This is a very cool short video showing a nifty little illusion. I had it figured out about 1/3 of the way through because, after all, I am a supergenius (or, more likely, I spent my youth and a goodly part of my adult life playing with illusions). Take a look:
2D/3D illusions like this are really fun, but also something to keep in mind with a lot in visual sciences; our brains are so easy to fool with such things, making us think objects are closer or farther, smaller or bigger, than they really are. If only most UFO enthusiasts could appreciate this…
