internal mindmap client?

[TimP]

What people call mindmaps generally aren't mindmaps - they're network diagrams. Mindmapping is a technique for brainstorming that few people use properly, the result of which is a network diagram to share with others.

With UR's ability to handle multiple parents per child, network diagrams as an alternate view to the tree would be very useful. Further, make them viewable in a web browser with a selected list of attributes displayed with each node and another list popping up with a click.

I don't know about floating, 3D views though. Fun indeed, but controlling the visual overload would take practice.
