Hi Paul,
thanks for your interest.
My earlier frms and pars are available on Spanky`s Fractint homepage
http://spanky.triumf.ca/pub/fractals/formulas/
 
Multi5.frm is not yet available as yet. It is the complete formula
collection for my present submission.
I will mail it to Spanky tomorrow (and on the list in some parts if wanted).
I also have a  big file with the old frms and a basic update for many of them,
I will mail it to you as a zip file if your interested. 
Multi4.frm  features an earlier version of my "3d" effects where
I used the iteration of the previous pixel to calculate the
"warp" effect, but it tended to be distorted in some parts for
obvious reasons.Double iteration was the solution, but anyway,
 Multi4 features some interesting pictures I think.
 
Fractal Greetings,
Al
