Perhaps I'm just out of the loop, but what do you intend to do with your stream of random numbers? You going to send a tape to your friends under armed guard? Just curious. Oh, I built a hardware random number generator a few years ago for some ESP experiments I was doing. I wanted to see if computer hackers had better odds of affecting the output of a RNG than non-hackers. (You know, the hacker walks into the room and suddenly the broken piece of equipment starts working?) Turns out they can. -simson
