Making the Pendulum.
I started off by using the cylinder to create the head and the tail for the pendulum and used the sphere as the twisting point. I then used the creative joints to make it movable, but to make it easier to animate I used the NURBS Circle.
While animating it, there were some problems that uncured. First of whenever I tried making it flip it would always glitch.
Animating the pendulum helped me understand follow threw in a 3D space. Even dow the pendulum is not that great and has some problems here and there, it still helped.
