I've been experimenting with the Unity Game Engine and have been playing with some other tools, I've made this demo here experimenting with realtime mesh deformation...

DeformationDemo
(you need to install a web player to play with it...)

and have been working on car physics for use in a racing game...

I've made this model here for use in the game when I get to the point where it works reasonably well...

I'll get back to Orange Runner 2 soon... but for now... I'm taking a break...
