Hello org-mode users!

A few months ago Leo suggested using org with tikz for generating
mindmaps.  I finally got a bit of free time last night (wife is out of
town) and put together the attached file.

Also attached is an example org file, and the output (in PDF).  I do
need a bit of help finishing this off though.  I'm not quiet sure how to
get TikZ to do a better job with the layout of the mindmap when you have
several nodes.

All the example mindmaps have only a handful of nodes, and were all laid
out by hand.

Anyone want to help me get this mindmap generator finished?
