Very cool map to explore the Microsoft office features and it is a WPF application ;)
you can download it from "Microsoft Office Interactive Developer Map"
The Microsoft Office Interactive Developer Map is a Windows Presentation Foundation (WPF) application that helps developers visualize the different programs, servers, services, and tools that will help them build solutions. It allows them to drill down to each product and technology and learn about new features, objects, Web services, namespaces, and schemas required to extend Microsoft Office and build custom Office Business Applications (OBAs).
