This month I've been using Ultra Fractal to make illustrations based on drawing prompts generated by an AI. Kind of a frivolous exercise, but it has definitely sharpened up my techniques for using coloring formulas.

In fact, if you scroll far enough, you can see the ones I made for last year's prompts, which I think were better suited to fractals than this year's. I can post parameters if anyone's curious; I think I mostly used the public formulas.
Here's what I made for the prompt "CLOCKFUL-LOOKING SCIENTIFIC SPHERE"
