Flex based dynamic graph navigator for drupal website

I've constructed a force directed graph interface (like the Visual Theasarus) using drupal nodes and tags as a navigation interface for my website. I've hacked the freemind module to output the structure of the site as an xml, with a further python script to massage it further (as my php is pretty rudimentary). The viewer is flash based built using flex and the Springraph component from Mark Shepard of adobe http://mark-shepherd.com/blog/2006/11/17/a-flex-component-for-graph-visu....

The launch page for the navigator is here: http://toolshed.artschool.utas.edu.au/billhart/phd/sitemap, there is also a video only version (but requires the current beta of flash player 9 to support h264 mpeg4).

I probably don't have time to clean it up for release as a module in the near future, but if anyone is interested I'm happy to supply what I've done.
