More than fifty years ago Leonard Read wrote his famous essay, I, Pencil: My Family Tree as told to Leonard E. Read." It has been used in economics classes ever since to help students get a sense of the incredible complexity of market economies. The free market think tank, The Competitive Enterprise Institute, has made a six minute video that tells the I, Pencil story. There clearly is an advocacy component at the end of video but the video tells the story quite well.
The Institute for Faith, Work & Economics has also done a video that features the same ideas using a new ubiquitous technology, "I, Smartphone."
