Ok, no language holy wars. This was quickie to test out the Noise Sphere plotting. It's in Pascal, but it's understandable.

Odd... That came through on the mail/news gateway but the preceeding article that explains what that was about didn't.... did anyone receive it? In case no, it's based on Clifford A. Pickover's paper "Random Number Generators: Pretty Good Ones are Easy to Find" which doesn't deal with useful RNGs for crypto sense, but the paper does explain ways to visually represent RNGs so that seemingly good RNGs show their awful correlations, etc. My previous post that should have showed up mentioned that these methods might be useful for checking out crypto functions (hashes, pRNGs, ciphers).
