Jeremy Miller has been commissioned by Addison Wesley to write a book on Presentation Patterns. He has chosen to do this the Martin Fowler way by using a wiki engine and making it available to the public as he writes it. This book is targeted directly at the “How”s of writing desktop applications and rich clients using WPF and Silverlight. Here is a brief description from the site:

Inside of an enterprise application, the user interface layer can be very complex in its own right and is a huge source of potential bugs because of the element of human interaction. This book will present the design patterns that can be used to manage the complexity of user interface code. The book will discuss patterns for organizing the responsibilities of a single screen, coordinating the activities of multiple screens within an application, and architecting a structure that allows a desktop application to be efficiently extended over a longer lifecycle.
