Surviving Worm

This is a blowup of the worm-like detail in the lower right in the previous deviation Bleeding in the Ice Water. That is it’s a magnification in a 2D-slice of the four dimensional cubic parameter space using the standard parameterizing z -> z^3 - 3a^2 z + b, critical points z = +a (making the set M+) and z = -a (making the set M-).

Software: Ultra Fractal.
Color routine: Continuos Potential Method (CPM).
Formula: Cubic Parameterspace3 in the sp3-module written by my dear friend Greenseng here at DeviantART. All his modules, as well as mine can be downloaded here.

Below the parameter file, play and have fun
