I don't want to pour pour cold water on your project, but it seems to me 
that Arbaro, Pov-tree and/or Tom-tree have already beaten you to the punch 
in creating organic-looking trees. However, as an exercise in refreshing 
your understanding of the SDL - not a bad idea. Now if you could produce a 
macro to generate isosufaces that mimic trees you be onto a real winner :-))
BTW, welcome back. I too was away for a time but its hard to say no when 
POVray sidles up to you, slips its little hand into yours and says "Just 
once more, for old times sake".
