The folks over at http://thirteen23.com/ have some snazzy examples of “the art of the possible” when using the Windows Presentation Foundation. You can download 4 WPF application samples. You’ll need to install WinFX Beta 2. If you don’t want to install WinFX Beta 2, but want to see what’s possible, they have videos of the apps running for download. It’s amazing when you couple artistic talent with cool technology! My favorite is the Harmony sample. There is a bit of setup work to get it running, but it’s pretty cool!
