That is correct. In fact semiconductor logic is done using these two
principle gates. See http://en.wikipedia.org/wiki/NAND_logic . Quite
interesting

The book Laws of Form, by Spencer-Brown' is based on that observation,
with nand/nor expanded to n-ary 'bag' functions (like sum() is).

First question: what's an exotic logics?
Do you mean things like thr
I was staring at a logic table the other day, and I asked myself,
"what if one wanted to play with exotic logics; how might one do it?"
I did some searching but not being too sure of what to look for and
carried away with my own enthusiasm for the idea, I didn't find much.
