I found this image of a Thaumatrope that seemed to me more detailed that others that I have stumbled across. The two images in this video combine to make the illusion of a man grabbing a baby caff by the tail. Each image is placed on separate sides on a circular object which have string that emerges from both sides. When the string is stun, the two images combine based on the way the human eye captures the visuals in the retina. One famous movie uses the Bird in the Cage thaumatrope as a essence of relative calmness. This can be seen in the Tim Burton film Sleepy Hollow.
