I have made a simulation with point movement (brown) first and then rig the model with springy mechanisms (pink).

There are two main benefits with springy mechanism compared to point motion:
1) Translation of the points is really like a rotation in bone motion. In point motion you have to insert more keyframes or play with the interpolation to achieve a better rotation.
2) With springy mechanism I have any angle rotation already done. If you want to rotate in the opposite direction with point motion only you have to redo the movement. With springy you have it already because the model is rigged ready to rotate. Also you can stop at any angle and play with the model in that angle. With point motion you need to keyframe all the points and then the interpolation fails to reach that angle at the desired velocity. This is the most important benefit of the use of the 3D rig technique.
The main problem is that you have to create your model in a way that cna be animated with the fewest point movement.
For the moment I have an eye, a hand, a leg a WIP foot and and a nose... what happen if I combine all them together??
Please critics and comments are welcome. And also I have to receive your comments about the drawing itself. You know I'm not a very good drawer and will appreciate any comment from your experience.
