A Double Pendulum

Here we can see the chaotic nature of the double pendulum. By clicking on different portions of the screen, you can release the pendulums from different locations. No two releases will be the same. You can explore more about chaos and the double pendulum here.
Note: Becuase I used a simple integrator in this model there is some numerical excitation so I added in some dampening to the dynamics to cancel it out.

Add suitable fallback here.
