The parent fractal of this motive is Figure 3 in the article 19b) Short manual to the module Cubic Parameterspace 3 [link] contained in my Chaotic series [link]

The “bloody” area, having more structures than the black, are NOT the results of any filter or post processing, but an authentic part of the very mathematical terrain in this area

Below the UF parameter file. Play and have fun
