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:

Or, you can draw it yourself with the rediscovered original parameter file (courtesy Paul Lee):
