Simply amazing presentation from Blaise Aguera y Arcas where he demos new augmented-reality mapping technology from Microsoft

Paul Yanez is building a nice collection of simple Silverlight Tutorials. The thing I like about this list is that the tutorials are short and sweet, covering some basic principles that any designer can pick up quickly and expand upon.

.toolbox, a fun online learning environment, where you will learn basic design concepts and how to apply them, as well as the fundamentals of creating Silverlight applications using the Expression Studio tools.

SLARToolkit is an open source Augmented Reality Toolkit for Silverlight.

Sweet video promo for the .toolbox design program
