Thanks Curtis,

I have been eyeballing some of the examples out there.  Here is one  
that draws my eye... http://tinyurl.com/2aqeqn  I had hopes of  
finding an ImageJ-centric implementation of a quadtree - something  
that already exploits ImageJ's Roi object and graphics.  I'll give it  
a whack sometime soon.

Cheers,
Ben
