The goal of this project is to create a control system that will dynamically simulate the interactions of two active bodies (probably using some sort of state machine.) Active body simulations interacting with one another are interesting because each simulation has to react not only to itself, but they also have to be able to act and react to each other. For instance, an active body must take into account not only the forces it exerts upon itself, but also the forces it encounters through contact with the other active body. This behavior gets more difficult to simulate as the type of behavior being simulated gets more complex.

This type of simulation will be the building block for more complex multi-active body simulations. For instance as a starting point, I would like to be able to show two human characters playing "patty-cake." This interaction could be between two adult characters, or it could be extended to an adult and a child or even two children. Building on this concept, multi-active body simulations could be created to simulate a lot of interactions such as a horse and its rider, two ballet dancers doing lifts or combined steps, or even a parent carrying a wiggling child.
