Sand is a thing between sea and land - Referencing #8

In the first sequence chosen for presentation, a child character stumbles and climbs a small slope.

Within the story world, the child is lost, tired and unused to his surroundings. The environment is made entirely from loose refuse, crushed plastic bottles and cans. This was emulated in the reference video by sand.

This video has been broken down to examine key frames, limb placement and centre of gravity (CoG). As the subject falls we can see her CoG moving away from the equilibrium point (represented by the vertical blue lines).

Through the sequence, the subject transitions from bipedal to quadrupedal movement. Some elements of Williams'  classic biped animation remain despite this transition with contact points, passing positions and a rise, fall and roll of hips and shoulders.
