A simple 2D physics demo for Silverlight 1.1 Alpha. This uses a managed version of the Bullet Physics library. Should run great on Windows or Mac, in IE, Firefox or Safari! (it'll give a download link for the Silverlight 1.1 Alpha plug-in if you don't already have it).

The source code for my XBAP 2D physics demo is now available. Enjoy!
