Powers of Ten (1977) [video] (youtube.com)

This is so classic, the Simpsons parodied it https://www.youtube.com/watch?v=FEuEx1jnt0M

When I was a kid the local science museum had this version on a film loop.

Now the local science museum has Cosmic Eye (https://en.wikipedia.org/wiki/Cosmic_Eye)[1] on a loop, which was inspired by Powers of Ten and by Cosmic Zoom[2]

I have this book, it's great

Obligatory a variant with Gas - Microscopic as the soundtrack: https://youtu.be/NvG-jqGsWSk

It always amused me on how good it fit.

Always loved this film. I made a zoomable timeline that scales to all of time, that was partly inspired by it:

Watching this film: YOU are big, YOU are small, YOU are everywhere, at all scales.
