This brief film is not very long, does not have much of a plot, and does not garner many laughs, but it's so, so fascinating.

The scientists used a scanning tunneling microscope as their animation tool. The pixels are individual atoms, nudged into place to form a picture. (The Guinness folks have certified this as the smallest movie ever made.)

What's a scanning tunneling microscope, you ask? It's an instrument for imaging surfaces at the atomic level; the development in 1981 earned its inventors,Gerd Binnig and Heinrich Rohrer (at IBM Zurich), the Nobel Prize for Physics in 1986.

In the film, a blocky figure  interacts with an individual atom in a variety of ways before the credits, which spell out both “THINK” and “IBM” using  individual atoms to form the words.
