Me finding out why recursion is such a nice thing, and why large amounts of coding may point to an error in the way you are coding ( less is more.)  After 2 iterations of lots of code I stumbled upon  (from doodling in my sketchbook) the recursive way of doing what I wanted, and got it down to a small fraction of code that worked perfectly for me.

The above link has an animated gif showing the different levels of recursion (along with the code.)
