WHITE PLAINS, N.Y. — Scientists have taken the idea of a film short down to new levels. Molecular levels.

IBM says it has made the tiniest stop-motion movie ever — a one-minute video of individual carbon monoxide molecules repeatedly rearranged to show a boy dancing, throwing a ball and bouncing on a trampoline.

Each frame measures 45 by 25 nanometers — there are 25 million nanometers in an inch — but hugely magnified, the movie (http://bit.ly/17ZmHIt ) is reminiscent of early video games, particularly when the boy bounces the ball off the side of the frame accompanied by simple music and sound effects.

The movie is titled "A Boy and His Atom."
