I tried reading the article (after giving it a go with babelfish first) but
it's too
complicated for me. Would you mind sharing the .pov and possibly the .ini ?

I tried averaging 160 sine_wave gradients then rotating and scaling
semi-randomly
but the effect is nothing like with your approach. So how about atleast
giving the
rest of us atleast a clue
