It's all about rendering -- how you render or flesh out the bones of a formula -- and less about what that formula itself can do.
It's taken me a few years to see that, although it ought to have been pretty obvious. You can see it easily when you compare the outputs of several different fractal programs: similar formulas produce things that look very different. Or to put it in more practical terms: what produces something great in one program can produce something mediocre in another.
In InkBlot Kaos, the main menu has a category called, "Filters". This selection is what really makes or breaks the image. The RGB color sliders are similar; they determines whether you get a fractal Vermeer or a fractal Ver-junk.
I guess that means it's important to have a program that gives you many rendering options. But InkBlot Kaos, surprisingly, only has one!
When it comes to making art by pushing buttons and turning dials, you just have to try things out if you want to learn anything. Success is often not where you'd expect it to be.
