I've got a short program for the PC (w/TPascal source) that plots a noise sphere from a file of (pseudo) random data, if anyone is interested. Requires a VGA card that handles mode 5Fh (640 x 480, 256 color) though the source can be eaily recompiled to use something else, or standard Borland Graphics drivers. Send a reply with the subject "send nsphere" or check ftp.funet.fi in the /pub/crypt/random directory in a few days [the ftp site would be easier on my mailer ;] The source has a brief explanation of what noise spheres are and a reference to the Pickover article the program was based on. The source code is not copyrighted, and it would be nice to see it ported to other systems, or maybe a portable C version that writes the output to a .PCX file in RBG(?). [I'm not that fluent in C to write one...] I've gotten some *very* interesting results. Raw samples collected from fast timings between Windows message broadcasts do nicely with some of the randomness tests (compressability, Maurer, chi-sq) but clearly plots a spiral. Raw samples from the keyboard don't do as nicely in other tests (~50% compressability, <6 bits/byte Maurer, and "non-random" in chi-squared] but in the plot no discernable pattern shows up.... similar to plotting the output from /dev/urandom [even when /dev/urandom was configured *not* to use keyboard...] Needless to say this will affect sampling methoids in the next version of NOISE.SYS. take care, Rob --- Send a blank message with the subject "send pgp-key" (not in quotes) to <WlkngOwl@unix.asb.com> for a copy of my PGP key.
