First here's the movie itself, a cute little story of a boy who plays with an atom:
Then we get the 'making of' story which explains how the movie was made by moving around actual atoms to make a picture. It also tries to give an idea of how tiny atoms are.
What I really like about the video is the way they have managed to explain the research that their bit of fun is really part of. They are trying to find ways to dramatically increase the capacity of our storage devices by making transistors really, really small.
This is a problem that will make sense to kids and makes nanotechnology very understandable.
The video itself is also a call to encourage more kids to take up a career in science.
