Latest Animation
This is a character that I modeled, rigged and have animated. He's an anteater who is after an ant, but he's a bit of a klutz so he trips over his own feet and falls down.

Here I've done a walk cycle with the bat character from Bait. The most recent rig is also shown after a few loops of the walk cycle. I've used splineIK out the wazoo for this fellow. I've also implemented the new fix using MultiplyDivide nodes that is taught in The Art of Rigging: Volume 1. The splineIK and some clever scripting is what enables his wings to deform so brilliantly. It is beyond what I expected in that the deformation is almost perfect.
