Most of the source code for my physics demos is available on CodePlex (except for the WPF 2D one; I’ll get that moved at some point).  To save you from having to hunt around I’m listing the main ones here.  Enjoy! smile_teeth

Silverlight 1.1 2D (wheels)

One of my first Silverlight efforts, using the BulletX library; as soon as I get some time I’ll fix the irritating performance problem (stuttering frame rate), I promise!

WPF/XBAP 3D (beachballs)

One of my favorites (I like the specular highlights smile_regular) using the BulletX library.  Don’t forget you can rotate the whole scene by dragging, or zoom in/out by right-dragging.

WPF / Flade (controllable car)

The already awesome Flade engine demo, running as an XBAP.

WPF 2D (car, eggs)

Based on the Newton Dynamics engine.  This would be sweet as an XBAP, but would need to use another (.NET based) physics engine such as BulletX
