Circuit diagrams

I was listening to a Feynman lecture on what computers are and started doodling logic circuits based on that. First I made a 1-bit adder, then extended that into a 2-bit adder, doodled a 3-bit adder and generalized from there to arbitrary n-bit adders. Then I made a 4-bit adder out of two 2-bit adders and drew this thing in Photoshop that generalizes the idea to 2n-bit adders. And tried building the rest of the logic gates using just NAND gates. Fun fun :)

I tested the logic gates and the 1-bit and 2-bit adders in JavaScript but haven't tested the 4-bit and n-bit adders.
