That is Octree, > http://www.octree.de. I have tested Octree quite fully and eventhough I agree it is quite powerful, I think it is not currently usable. It works with mouse mouvements (see the webpage). However if someone gets in it a command line (like in autocad), menus, and shortcuts (configurable of course) to get instand access to the "cards" as they call it, I think we have the base of a full scale serious project. You should try it out, just to see the work that has been done, eventhought the UI is to be completed (that should not be to dificult) Good luck with your work, I admire it.
