Description
Stumbled upon this fractal while going through some old files, I never did a final render of it back then for some reason. Considered increasing the maximal iteration to have more "free floating" elements, but I liked the look of the more connected version.

The spiralling details makes me think of spines and Aliens.

Hollow Julia fractals tend to be slow to render since they contain "infinity poles" with a derived distance estimator, this one have even more than normal, and combined with a thin outer shell it is even worse. The scaling factor of the DE was ridicules low and I considered doing an ambient occlusion render of it only, however some experimenting with a modifier of the DE stepping turned up a very simple solution that both solved the infinity poles and intersection of the thin areas, which lead to a much faster render (still horrible slow, but worth doing). Did some experimenting with lighting as well. Rendering done with my own software.

Enjoy.
