Binary Adder Made From Wood

Several years ago in a far off land I was a computer science student. One of my classes was comprised of little more than counting adding subtracting, living, binary numbers. This machine would have been great to have, not just because it is sweet (it is) but because it would have given me something to do while I let my brain recover from all those ones and zeros.

Also if the world were to end, and the few humans to survive couldn’t get windows to boot, they could start the great task of building a grand wooden computer. I don’t know why, just because they could (isn’t that why we do anything?).
