He wrote a 64 bit OS from scratch where the shell uses C as it's scripting language, and I believe everything runs in Ring 0. Also no protected or virtual memory. So if you go over on an array index, well you could screw up some of the kernel memory space. Brilliant, but crazy. See above, and read some of his comments. He seems to be some sort of fundamentalist christian, and IIRC his comments were about saving everyone though Jesus or some such thing.

Take a look at his comment history (turn showdead on first)[1]. He's a somewhat eccentric character.
