These fractal images were generated using Ultra Fractal version 5.04 which is a Windows program and may be obtained from here.

This work is the result of explorations of the parameter and formula files published daily by Jim Muth on the Fractint list which is archived here.

Jim's wonderful collection of fractal images can be viewed here.

Fractint, the DOS software which Jim used to create his fractal images can be obtained here.
