Chladni Figures

There is an interesting music video[1] by Nigel Stanford featuring Chladni plates among other cool phenomena. That's how I first learned about Chladni plates

These figures could be the universal pictoral symbols for numbers. I especially like the triangle figures since the triangle is the 2D simplex.

Also known as vibration node patterns or modal patterns. Useful to find resonances.

> When Chladni showed the technique in Paris, Napoleon set a prize for the best mathematical explanation. Sophie Germain's answer, although rejected due to flaws, was the only entry with the correct approach.

Science and Mathematics visibly take time and effort not a contest and some goodwill.

which programming framework would best allow the coding of an app to generate Chladni figures on an arbitrarily user drawn shape? And perhaps with a knob to allow frequency modulation. Or perhaps two or three knobs to allow visualization of harmonics. Would this allow a graphical solution to Schrodinger's equations for one, two, three electron models?

What's with the habit people have of posting random things they just discovered and found interesting here. This isn't news.
