There are only 10 types of people in the world

...those who understand binary numeral system, and those who don't. (Sorry about the old joke; couldn't help myself.)

Matthias Wandell is most definitely one of those who do. He designed and constructed a calculator capable of adding 6-bit positive binary integers (that is, integers between 0 and 63). There wouldn't be anything extraordinary about it if not for the fact that the machine is made of wood and marbles. Below the fold is a video with some demonstrations; it's strangely mesmerizing.
