This illustration shows a bit of what you are reffering too. It builds off the spear hand and then locks the wrist and uses the turn for a throw. Going back to the idea of movement... I don't think it is so much that arts should not be stagnant but more that people should not be. At some stages of development people are very concrete and it is appropriate. When they begin to see grays instead of blacks and whites the are becoming more able to think abstractly. I think part of the challenge of teaching the whole individual is helping to usher them into a greater ability for abstraction and flexibility in thinking. Part of the task is biological and part is cognative. When the brain is ready the teacher and the techniques appear.
Hard weapon, soft target. Hard weapon soft target.
Blocks can lock.
Turns to throw.
