You just have to check out Zero Gravity, a cool and cute Silverlight puzzle game based at: http://www.ltbennett.com. This is the result of 4 weeks work from a team of 5 people (designers, developers, animators and artists) using Expression Design, Blend and Visual Studio to implement the designer/developer workflow improvements that we've been pushing with Silverlight and WPF.
You can read more on the experience of building it at: http://timheuer.com/blog/archive/2007/06/26/zerogravity.aspx
In addition, the main character of the game, Lieutenant bennett has his own FaceBook, MySpace and Twitter Pages.. :)
