I extended the Flex 3D example of my previous post some more. Now you can drag (left mousebutton) the objects and bounce them into each other.
WOW is based on APE , a 2D physics engine, and they both share the same problem. They aren’t really supporting colliding squares or cubes. You can set them on a fixed position but you can’t throw them free through the environment. But APE has wheelparticles that rotate if they collide. If I’m going to work futher on this project I’m going to use APE
