Calculate the Hilbert value of a point for use in a Hilbert R-Tree?

I have an application where a Hilbert R-Tree (wikipedia) (citeseer) would seem to be an appropriate data structure. Specifically, it requires reasonably fast spatial queries over a data set that will experience a lot of updates. However, as far as I can see, none of the descriptions of the algorithms for this data structure even mentio...

Hilbert tree: Does anyone know where to find a code implementation of this?

I'm looking for the code or even a visual demo on how this tree works. I have read this paper on Hilbert R-Trees and tried to implement the algorithms stated I get lost when I have to adjust the tree with the sets, as well as not sure on most other things. It doesn't matter what language if there is an implementation as it will be used...
