Hi! Thanks for your comment! It’s interesting. I don’t think there is any magic about cymatics per se: it depends on how sound interacts with physical objects, and these objects have certain resonant frequencies, which is when the start to vibrate “interestingly”. I like it as a potential visualisation idea though!

That above isn't just an idea, it's the idea of sound visualization. It's a bijective projection between sound and shape that turns nice sound into nice shapes and vice versa. The analog sound visualizer would be an air filled glass sphere put next to speakers, if only we could see air. All you need is a performant software simulation of it. The only problem to solve here is visualizing the rapidly changing patterns in a comprehensible way. P.S. actually, we can see air patterns if we fill that glass sphere with dust. Edit: In fact, that's been done already. Find the "Yantara Jiro voice made visible". They used a cymascope (a water bowl in lab conditions) and captured the formed patterns with a fast camera. A water bowl is indeed a great music visualizer.

One could imagine making a “fake” cymatic visualisation while still looking interesting!
