In this '70s video clip by the office of Charles and Ray Eames for IBM, you can see the relative size of things in the universe. The clip starts with a view of a couple on a picnic, then the camera zooms out by a factor of ten farther. Every ten seconds, the view expands by a power of ten... Then it zooms back down, also in a power of ten, down to the quantum level ...

This kind of video reminds me of The Galaxy Song by The Monty Pythons [Youtube].
