I remember some videos from a few years ago that featured music generated that when the output was connected to an oscilloscope it would create some interesting geometric patterns but I can't see to find those videos anymore -- anyone know what I'm talking about? The music was kind of a EDM like thing that was not terrible from a purely musical standpoint but it produced some interesting patterns as well. I think this was either 2015 or, more likely, 2016. I wish I could be more descriptive but it's been a few years.
