I'm having problems with the tree in the attatched image.  For one
thing, I'm unable to be certain that it's not passing through any of the
surfaces in the scene, though that isn't a major problem.  Yet.
    The current problem is that the secondary limbs are more evenly
distributed on the primary branches than the latter are on the trunk.
The tree seems far too a-symetrical to stand upright.
    While I love how the addition of the tree brings a sense of "Life"
to the scene,  I can't use it the way it is.  I used Giles Tran's
maketree macro to generate the treee but I have absolutely no idea of
how to get it to distribute the branches more evenly.  Is this even
possible?
    Any suggestions would be appreciated.

It's a while since I've used Gilles's macro, but I would suggest trying
different seeds (how appropriate!).

Gilles macro typically uses preset constants to determine the length of 
branches, density of branches, number of segments and so on across all 
the recursion levels.  What you can do is to substitute arrays for these 
constants and thus vary their value according to the recursion level 
being processed.  This technique is used, iirc, in the tomtree macro. 
Of course it makes it more complicted to change the number of recursion 
levels.
