Burning ship version of Pauldebrot formula is quite an intriguing. Actualy not all of them, but a version what is generated when z seed is small fractional number but a W seed aproaches zero with w= 0 representing singularity a normal mandelbrot set.

It have interesting quadratic symmetric julia set, maybe with parameter tweaking one can get julia set of perfect circular figures.

Zoom in somewhere in middle of m-set. In smooth colouring, when min and max iter parameters are what statistics say, sigmoid transfer function gives the most accurate results (but only then).

Looks like a variant of the Burning Ship to me.
