German cameraman Chris Fay recently posted on YouTube a neat video showing what happens when the frames per second on a camera and the speed of a helicopter rotor are perfectly aligned. The helicopter blades appear not to rotate at all. And the helicopter hovers magically in the air. Even when you know the mechanics of the illusion, it’s fun to watch.
