What logical path do you mean, bib?

Just knew that a julia at 0,0,0 makes a sphere and the translate was one of the few i could make any sense of...
a combination of experience and feeling

Escape time fractals are not really intuitive for me, creating something you have in mind is hardly to realize with it.
OK, I did not notice you took a (0,0,0) julia as a starting point. Now that's clearer.
Yesterday I showed my fractals to my grandmother and she asked me: "Can you make a snake that looks like a real snake?"
That's the problem with fractal design. Even with a lot of experience (not me because it's been only 2 years since I do that "seriously"), I feel that there is too much trial and error instead of a deterministic "artistic" process. The case of the torus solved here is a counter example, but very simple.
So, can anyone do a snake that looks like a real snake? No photoshop please!
