Seen this a few years ago - If you click on the "show more" he mentions how it was done
"What you see is what you hear: The audio signal is fed directly into the oscilloscope, where vector graphics are drawn with sound.
Filmed from an analog Tektronix 5103N scope.
left audio channel: horizontal deflection
right audio channel: vertical deflection
software used: Max MSP (spiral objects, etc.), OsciStudio & blender (teapot orbit & wireframe 3D objects), Ableton Live
so yeah suspicions confirmed 'tis not quite what it seems (but still a nice concept and better than anything I could come up with)
