IBM's bleeding-edge nanophysicists have created the world's smallest movie (embedded below), by moving single carbon atoms around a copper surface. The film, called A Boy and His Atom, is 60 seconds long and made of 242 individual stop-motion frames, with each frame being roughly 50 atoms wide. So you have some idea of this truly minute scale, a human hair is about 1,000,000 atoms wide. If IBM so wished, it could convert A Boy And His Atom into a feature film, and still fit the frames within the width of a human hair.
