Chladni figures were geometric figures first discovered by Robert Hooke in 1680 and was researched and published by Ernst Chladni in 1787. These geometric figures are typically rendered on a rigid, vibrating membrane made from materials such as metal, plastic, glass, or bowl, covered with grains, like salt and sand, and changes shapes in response to different sounds that are transmitted by mediums such as speakers and actuators. The study of such phenomena is also known as cymatics. Chladni is able to simulate the phenomena digitally. A further 3 programs can be displayed by pressing and holding each of the 3 mode buttons.
