Woodstock was a prototype; a “proof of concept” which really caught on and matured. After I published the Woodstock article a good friend and cohort in WPF crime, Karl Shifflett, began working on a better WPF visualizer. After a couple weeks of us discussing, prototyping, emailing code snippets, sharing/critiquing ideas, and him working around the clock, he finally published an article about it. His WPF visualizer, called Mole, is now publicly available, just waiting for WPF developers to download it and put it to use.
I highly recommend that you check out Mole. It is the WPF visualizer. Forget about Woodstock, use Mole!
