I've always been fascinated by the patterns that can be created via musical notes. This video is an attempt to visualise a few of them.
Each of the nine sections represents a single part in the musical composition.
The video was made entirely using Processing, with Virtual Dub and AviSynth used in compositing. All free software - many thanks to the creators.

Thanks to Damien Di Fede on GitHub, without whose article on offline FFT, I'd have struggled to produce this.
