There is a Community Technology Preview release of the Team Foundation Server Sticky Buddy digital dashboard project that is built using Windows Presentation Foundation (WPF). I have used the source code from the Family.Show project to create functionality and a look that is appealing.
You can download it from the Codeplex site and you can raise bugs with the issue tracker...
Please remember that this is a CTP and is not fully functional. With this version you can see how your Areas and Iterations tree diagrammatically. I intend to display the work items within the body of the node and display a different view depending on the zoom level...
I have yet to skin the whole application so you will see some bitts that look exactly like the Family.Show application from Vertigo... yes I know.. I am a lazy developer...
