Indeed.

The [h] bit is really hard to predict. sin and cos are often
continuous and tan is rarely so.

I'll dig up my old sources if they've survived the cleaning.

I have. I've rendered about 15k fractals to date. Most of them being
random, hardly any are of any use :) But I'll see what I can do.

A neat trick I've done often is to choose two good-looking fractals
and do an anim by interpolating between parameters. Makes for some
cool morphing :)
