Chladni Nested
On rectangular plate, implementation of a frequency "nested inside another frequency", a product combination of two frequencies that produces more fractal like graphics.
Cymatics, a term introduced by the Swiss physician Jan Jenny in his book *Cymatics: The Study of Wave Phenomena*, was originally coined by the German scientist Ernst Chladni, who demonstrated the existence of geometric patterns caused by acoustic vibrations applied to sand or salt deposited on metal plates. The corresponding equations were derived by the French mathematician Sophie Germain (1776–1831). Thanks to these equations, it is possible to simulate and graphically represent these waves.”
