Expression Blend Release Candidate 1 is now available for download.  The product keeps getting better, able to render more on its design surface, more stable, better documented and tons of great new samples.  The samples are quite crisp from a design point of view with a designer's eye.  If you want to get the actual source and assets, you'll have to download Blend, but if you want to just check them out,  I've posted screenshots of all six and uploaded them via ClickOnce using the Publish Wizard in Visual Studio so that you can run them directly:

Animation Studio: This is a nifty little animation drawing tool. 

Color Swatch: An app that allows you do envision different color possibilities for interior decorating.


GrandPiano: Play the piano!


Photo Book: Flipping a book of images using 2 1/2 D.

Video Shelf: Video mapped onto 3D planes, library like navigation.
