hyperbolic trees

I have been playing with the hyperbolic viewer a bit too, ever since I saw it in use many months ago on Treebase.  It seems to me that it is a
very useful way to view cladograms overlayed onto a map because you can, in effect, zoom to a given area and expand the tree there.  However,
I haven't been able to make that work so, at this point, it is just an idea that I would like for someone to pursue.  For me, it is an awkward
way to view a phylogenetic tree by itself and simple tiered zooming methods (like on the tree of life) are much better because characters and
branch attributes are easily presented.  It is really nice to see improvements over the dotted line technology often employed on the web
though. Good luck with it.
