You should see this one!
http://www.youtube.com/watch?v=s1i-dnAH9Y4
It's 41 minutes long and entitled "Mechanical Computer - Basic Mechanisms In Fire Control", and it's a 1960's military educational movie about mechanical computers aboard ships for fire control.
They explain how everything happens analogue with mechanical parts: addition, multiplication, 2D functions, etc...
I found it extremely interesting.
