This is a test animation of my physics-based simulation rig for Georgiana's toy "space bunny" from the "Lunatics!" pilot.

I was having difficulty animating this realistically, so I decided to try simulating it. The idea is that the core of the model will be parented to Georgiana's hand or the belt strap holding it, and the physics will determine the rest of the movement.

It's a qualified success, but there are still some issues. The collision with the floor (and the cube) seems to happen well outside their apparent boundaries, and there is an odd sort of oscillation that I can't seem to get rid of. However, the overall movement is pretty good, particularly when it is not interacting with passive rigid body world objects.
