In 1998, the paper dragon illusion was inspired by Jerry Andrus for a celebration of Martin Gardner, one of the great mathematical games minds of our time. This is one of the most superb illusions you will ever see. We've all seen pictures of people where the eyes seem to follow wherever you go. In this illusion, the entire head of the dragon seems to move as you move. In fact, the effect is the same vertically as the head seems to move up and down with you. It is simply a paper cutout from complex angles that are joined together to create this wonderful sensory stimulation. Enjoy.
