I came across some old videos on Engadget about old fashioned mechanical design.
This particular one is about some old balistics computer. And by using cams etc. it calculates quite a lot of things.
Anyways I thought it might be cool as most of us are quite spoiled with microcontrollers.

Yep, the old ANALOG COMPUTERS. Also used in submarines during WWII for setting up torpedos. Turned all the knobs and set all the dials and made teh mechanical setting in the torpedo and then it was launched.

Speaking of analog computers, many don't know that Heathkit's first computer offering wasn't a digital one but rather a analog one:

 Acquired knowledge and experience can overcome such fears. Lacking those, then fear is probably a good thing. First step to replacing those fears with respect is through proper education.
