I haven't even *finished* high school and I'm not having any problems predicting
what the results of a iso-surface will be.  Of course I'm no math whiz but I've
been doing Povray for about 3 years. My advice?  Test all the functions
(abs,sin,tan,max,etc.) and the try to combine them.(abs(x+sqr(y)+sin(z))
Good luck!
