I see your point moomoose, it is very unlikely that Zanz would throw away his own art, so not much point pursuing this then.
Nevertheless, just for my own nostalgia, I actually found my original Mandelbrot page and put some images and links from that into my previous post above.
BTW, I never meant for the Google images to be used, I just pointed to them as examples to see how Mandelbrot spirals look like in case people find those an interesting base idea. You can see my original wording: " why not look at some of the spiral-type magnifications..."
