This is the same motive as my illustration [link] to my journal Finding the Path [link] , however in wallpaper resolution and without markings The motive is also rotated 90 degrees to the left in order to be a nice wallpaper

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 and z = -a.

*a_real = 0.6
*a_imag = 0
*b_real = #pixel (horizontal)
*b_imag = #pixel (vertical)

Only M+ is displayed, the motive being entiraly inside M-.

No filters or post processing except anti-aliasing.

Ultra Fractal, formula Cubic Parameterspace3 in the sp3-module written by my dear friend Stig Pettersson, Greenseng here at DeviantART. All his modules, as well as mine can be downloaded from [link]

Below the parameter file. Play and have fun
