Did you know that Henry Ford became popular in the early 1900's due to the assembly line rather than his creation of the Model A and Model T?
Almost everything around us is created by some sort of assembly line; either by human or machine.
Even this video includes it.
This video, by Isobel Knowles, started with just a single character known as Cat Rabbit, but eventually became a child's book called Owl Know How. Cat and Isobel are the partners that work on these videos and books.
They even have workshops for children to attend in which they teach participants how to make puppets.
