This song is good and I saw a CGMatter tutorial about creating an audio visualizer in Blender. I wanted to build a 2D Ruben’s tube (Pyro Board) around four years ago, but I couldn’t. This is the next best thing (although I will try to make an actual pyro board in Blender soon).

Creating the pendulums

I followed this tutorial by Polyfjord to create the simulation. It’s pretty straight forward and easy to follow, and I changed a few of the values to be better for my video. The main thing I modified was the pendulum frequency such that a full cycle for all ten pendulums was under a minute.
