After thinking about the hip and shoulder relations on some of the feminine figures of last week I wanted to break this down into a bone and joint model. I've used a simple stick model, exaggerating the movement in order to observe the seesaw effect of the movement line. There is a double helix of movement at the hips and this is mirrored by a smaller one in the shoulders. I've kept the bones a bit bendier in order to account for the spine and musculature as well as the animated effect of movement. It all seems simple but is crucial to the understanding of the three dimensional movement of the body, creating a flow of kinetic energy.
