Shadow puppets and stop motion both have similarities to one another. Both use physical objects to create motion using either light or a various amount of pictures in a sequence. They also have the advantage of being tangible, so you have more control over what the viewer sees at any given moment. However they differ in what they can show visually. With stop motion, you really aren’t as limited to what you can create compared to shadow puppets, where you have to create the puppets so they can work best when cast with light.
