Nice Longhorn videos

Here's a couple of nice videos showing off Longhorn features. Someone might have missed them, so... First there's the Commercial Real Estate concept video, which shows off a few cool Avalon graphics stuff. Then there's a pretty long MSDN TV episode called "A Lap around Longhorn" with Don and ChrisAn that is quite nice. It shows some XAML/Longhorn/Avalon/Indigo code. That show was posted some time ago, but it's still nice.
