The top plane of the first "Automatic Totalisator," designed by George Julius (1913). It was a mechanical computer designed for calculating and displaying bets at horse races.

There are more really awesome pictures of it, at this link:

Me toooooo. To me, this is more impressive than any digital computer could ever be. It's insane to imagine figuring out how to translate the physical movements into calculations.

Yeah, I didn't even consider that people had to actually MAKE THE PARTS and PUT THEM TOGETHER too, omg

absolutely !  
mind boggling to think of and engineer and then to build it is monumental.
I'm not sure you could find craftsmen who could actually build it today.
