thank you for all your replies!

jock: I'm quite new to UF although I still have a copy Winfract or Fractint
that came of a 5 1/4" floppy attached in the back of a '92 book called "Fractals for Windows by the Waite Group.

I have attached my first UF fractal with post processing using Real Draw Pro v3.1
however its not really the direction I want to go in. As I stated on the outset
I would like to explore the type of material images which you filed under your
mechanical gallery.

I tried loading your formula into UF, see attached jpeg
but I didnt see anything but a black backround.
all I was able to do was change the backround with some .uxf files
Is it possible for you to attach a .upr file that I could learn from
or send it via email ?

thanks!
