I've always wanted to build a replica of the Z1

http://www.pcgameshardware.com/screenshots/original/2008/12/...

It was a mechanical, binary computer. It ran at 1 Hz, had 1400 bits of memory, and it could add, subtract, multiply and divide. It even had a control unit which means it could run real computer programs. A 22 bit floating point multiply took 10 clock cycles.

And all of that in a completely mechanical system!
