Video: How does the Enigma Machine work?

Jared Owen writes:

I've seen many videos that have explained the Enigma Machine. Most of them explain it as a "Simple Circuit" and leave it at that. For this video I really wanted to dive deep - it's much more complicated than just an "On/Off Switch". The circuit goes all over the machine, and it took me a little bit to wrap my brain around it! What's more amazing is that is was invented about a 100 years ago - the precursor to the computer. I hope my animations helps others to understand - it was a lot of fun to make. Comments are always welcome, I'm continually trying to improve these animations.

Made with Blender 2.93 but rendered with Blender 3.0 - yeah for Cycles X!
