I never saw the real thing, but copies of it were all over the now (fittingly) long gone BBS's I was using at the time. I don't think Gibson did the distribution. The artists book at least was done by Dennis Ashbaugh[1] and he might have been behind the software as well? The concept apparently came from the publisher, Kevin Begos Jr.
