Vertically Driven Pendulum

For my final project in Classical Mechanics during undergrad, I decided to simulate different orientations of a vertically driven pendulum using VPython. Being a physics tutor at the time, I wanted to make this seemingly complex phenomenon more accessible to everyone and presented my simulation with this dramatic video made on iMovie that broke down the science a bit more. This video did not win an Oscar but it was nice to see through the comments on YouTube that people found it helpful in their understanding of the topic. If you watch the video, please let me know if you spot the flaw in one of the simulations!
