Very nice Lux. Looks like you've learned an emboss technique in UF you've used on recent fractals lately. I really like it. There's an embossed fractal in the UF examples. I'll have to study it & see if I can apply the technique to fractals. I've posted an entry in my journal referring to a few fractal formula courses Kerry Mitchell did that have embossing. I don't understand the math yet but he covers what's necessary to write formulas in UF. He explains how to write them very well even if you don't know the math you can still write formulas if you know the syntax & what to put in each section...that is the loop, int, default, etc. sections . He's a good teacher. If you want to learn about formula writing in UF I've got his email address there just email him & donate $25 & he'll send you a link to the courses.
