The three best visual illusions in the world were chosen at a recent gathering of neuroscientists and psychologists in Florida.
The winning entry may help explain why curve balls in baseball are so tricky to hit.
From the point of view of a batter, curve balls seem to "break," or move suddenly in a new direction.
The winning animation shows a spinning ball that, when watched directly, moves in a straight line, but when seen out of the corner of the eye, the spin of the ball fools the brain into thinking that the ball is curving. So as a baseball flies towards home plate, the moment when it passes from central to peripheral vision causes its direction to appear as a sudden jerk.
