Glad that you liked the video, using the magic whiteboard pens was definitely an interesting experience. As for the tools, unfortunately we don't currently have anything that is ready to try out. Our goal is definitely to have tools that people can use but
for now we are focused on experiementing with various development scenarios where this kind of visualization could be useful, how best convey information in the visualization (e.g. using color), and learing about the features of dgml (the new format for graph
drawing/navigation in VS 2k10).
