Loving spirals2

This is exactly the same motive as the previous Loving spirals [link] . However I Also love this reddish color map

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-).

*a_real = 0.1
*a_imag = #pixel (vertical)
*b_real = 0
*b_imag = #pixel (horizontal)

M+ and M- are plotted in separate layers.

No filters or post processing.

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]

More info about Cubics can be found at my Cubic Tutorial [link] and the
"cubic" articles in my Chaotic series [link]

Below the parameter file. Play and have fun
