One of the new cool features of the new Orcas TFS is the Team Build Job, which adds a kind of Continuous Integration to Team Foundation Server.
Jim Lamb, PM of this new feature, just released a Vista Sidebar Gadget that lets you monitor the builds happening on one server.
The screenshot at the right looks pretty familiar to me.
This gadget doesn't have an undocked view with more details about all the projects, but uses the flyout to show more details of a specific project then you click on the project name.
You can look at a preview of the TFS Team Build Monitor Vista Sidebar Gadget on Jim's post.
And if you missed it, you can look at a preview of my CruiseControl.NET Monitor Vista Sidebar Gadget, too.
Thanks to Thomas F. for pointing it out.
