#physics controller

The system uses all physics and inverse kinematics to move the little bird feet, resulting in some wiggly but endearing movement.

Mama and bb birds checkin out a snack.  An old gif from my physics/ik experiments I never shared.

This uses PID controllers to apply torques to all his body parts, which can add a lot of wobbly personality.  Sometimes too much.  But now the model will try to maintain the posture set by their IK system, while being fully, physically responsive.
