Together with James Waldrop, Mark Meadows developed a visualization tool for network Tierra. This tool use the VRML web browser as it's frontend. A network Tierra node, sends the data in it's complete TPing data array, via email, to a script which formats the data so that it can be visualized by the VRML browser. A complete description of the tool, as well as the visualization itself is available at:
