The pendulum exercise teaches about essential principles like arcs and overlapping action. All of the parts of the pendulum are affected differently from one another, so each part will overlap differently according to momentum and timing. I wanted my pendulum to look almost like a controllable drone, so I wanted to introduce some anticipation and a build-up of speed as it moved across the screen. I also wanted to play with how left and right momentum acts differently than rising/falling momentum, so I also included a small amount of up/down movement.
