Looks like the folks at Terralever have had fun with Silverlight 1.1... They built a very cool little zero-G game... I certainly had fun playing it for a while... well actually, I was "stress testing Silverlight 1.1 Alpha" ;-)
Read all about it: silverlight: who needs inertia, introducing lt. bennett
Here is my best shot so board so far... Can you get further??
Oh, and feel free to tell your boss you are just stress testing Silverlight ;-)
