Look at the center circles of Diagram (圖) A and Diagram B. Which of the centre circles looks larger?

It seems that our eyes are playing a joke on us. This often happens and we call it "Visual illusion" (視覺(jué)錯(cuò)誤).
Movie makers often make use of illusions. They make the objects around actors much smaller or bigger than usual. This makes us believe that the actors are much larger or smaller than they usually are. The movies Jurassic Park and Honey I shrunk the kids just make use of illusions.
