interesting link, thx paul

....my opinion is that he's way too wordy about what he's doing
.....and i'm wondering what software he uses to do the rendering.
this kind of potential field could easily be added to an ifs renderer,
which would be quite interesting indeed.
Yes, I thought the images were interesting as well, and wondered myself about the software involved. But in the email response I got from Thomas, he seemed to purposefully avoid mentioning the name. He also specifically stated:
"There is no fractal math or algorithmic process involved in my work. I have
consciously avoided that approach for particular reasons of my over-familiarity
with the look and limitations of fractal imagery."
I am still pursuing the topic with him through emails and hope to get further information that might really be useful.
