The scene itself has a gravity vector, and each object can have its own gravity vector set. So the scene can be set to (0, 0) gravity so everything stays in place except for interactions between shapes. I haven't played with that, but I like the idea of zero-G physics simulations. The damping value can be modified to simulate air resistance. > This is just a first version, so if you see features you'd like, let me >> know. >> > > I was gonna mention this on a physics learning list I'm on but got lost > looking for the physics engine you're using.

Calico has a physics engine of its own, which is based on the Farseer physics engine, which is based on Box2d. PyPhysicsSandbox is a layer on top of Pymunk, which is a Python binding to the Chipmunk physics library. The sandbox is independent of any IDE. > If you have any Youtubes or screencasts of your project in action, I'm > keen to view.
