3D t-rex drawn on an analogue oscilloscope 🦖

Curious if what we are hearing is the drawing or modulating the drawing per the video description:

"A 3D animated t-rex drawn on an analogue oscilloscope from 1982, with its redraw frequency modulated by MIDI from ‪@Ableton‬ Live. The amplitude of the audio left & right signals move the X/Y position of the beam which cycles through the vertices of the 3D mesh hundreds/thousands of times a second."

Update via Hexial: "The audio is creating the entire drawing you're seeing, moving the beam across the screen very quickly. The audio frequency is the number of times it's redrawing it per second."

"I'm using 2 synths (Serum) routed into the X and Y axis of the beam, changing pitch/effects with sine waves and saw waves.

Beware, if you listen to it on headphones it might make your brain go weird because it's panned hard left & right 🫠👌"
