I saw a thumbnail of a nice image on the FractInt Deep Zoom webpage. The image looked interesting but at the time there was no parameter file. What was there, was a short description of the history behind this image by Dewey Odhner. Quoting the FractInt Deep Zoom webpage: "This is a deepzoom image into the Mandelbrot using 63 decimal digits of precision. Dewey started this fractal and posted the partial image on the net when it was 2/3 completed after expending approximately 2343 hours of calculation time on a 486/33 computer." Wow, 2343 hours and still only a partial image. How did he ever find it and zoom in on a fractal that draws that slow? For an anti-aliased image, an answer, and more go to: http://www.fracton.org/fmlposts/spidrweb.html Or, you can draw it yourself with the rediscovered original parameter file (courtesy Paul Lee): spidrweb { ; (c) by Dewey Odhner.

Such an amazing difference between the calculation time back then and what may be achieved on today's desktop computers!!! Thank you for the image and this re-discovery. :-) I always thought that the removal of all those FractInt generated .GIF files from the old Spanky web site was such a loss of useful data and information. It would be great if they can be restored to the new revised Spanky web site.

The real thanks should go out to Paul Lee. I had run out of leads in finding the original color table. He found the original gif somewhere and then added the lost information to the FractInt Deep Zoom page. -- Mike Frazier www.fracton.org
