Small-scale film-making

As short animations go, A Boy And His Atom isn't obviously that interesting or clever - unless, that is, you consider that it was created by IBM by manipulating individual atoms. The film has to be magnified 100 million times for it to be visible to the naked human eye. Rumours that Tom Cruise was approached to play the part of the boy are unconfirmed.
