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?
