If you like videos like this, check out Retrotechtacular on Hackaday. They have a series on mechanical firing computers on navy ship that is nothing short of mech-eng porn, and I mean the classy kind.

That was amazing, thanks. I found the integrator and multiplier especially simple and clever.

I watched that whole series a year ago and was fascinated. I believe it has been posted here before but it's worth repeating.
