Cymatics
From Arcthon
Cymatics (from Greek: κῦμα "wave"), also known as modal phenomena, is the study of visible sound and vibration, typically on the surface of a plate, diaphragm, or membrane. Directly visualizing vibrations involves using sound to excite media often in the form of particles, pastes, and liquids. [1] The apparatus employed can be simple, such as a Chladni Plate[2] or advanced such as the CymaScope, a laboratory instrument that makes visible the inherent geometries within sound and music.
