The CLR team (or, more specifically, the BCL team) has a bunch of really cool demos that showcase new functionality in Whidbey’s Base Class Library.  The obligatory “Hello World” can be found in the Console Animation demo.  Coolest of all is the “Space Invaders” demo that shows what you can do with a plain ol’ Console application.  Of course, I was disappointed as I STILL SUCK at Space Invaders!!!
