I created this animation when I wrote my bachelor thesis about generative animations a year ago.
It was entirely coded in Processing (http://www.processing.org), no cuts no keyframes. I can't say this is the way to go when it comes to creating animations in general, but I definitely learned a ton when I created this.
The audio track was produced by Kiorda Däkin.
