World's Smallest Stop-Motion Film : A Boy and His Atom

A Boy and His Atom is a 2013 stop-motion animated short film released on YouTube by IBM Research. The movie tells the story of a boy and a wayward atom who meet and become friends. It depicts a boy playing with an atom that takes various forms. One minute in length, it was made by moving carbon monoxide molecules viewed with a scanning tunneling microscope, a device that magnifies them 100 million times. These two-atom molecules were literally moved to create images, which were then saved as individual frames to make the film. The movie has been recognized by the Guinness Book of World Records as the World's Smallest Stop-Motion Film.
