Alexander Lauterwasser is a German photographer and researcher, born in 1951, who built on Chladni and Hans Jenny to photograph water surfaces driven by sound. His 2002 book Wasser Klang Bilder (published in English in 2006 as Water Sound Images) used sources from pure sine tones to Beethoven and overtone singing.
This is a segment from the Franco-German broadcaster ARTE, re-uploaded in 2020 by a third-party channel called Lebendige Kultur. It is in German without subtitles, but the pictures carry it: you see the dish, the lighting and the patterns forming as the frequency shifts. If you have wondered how he gets the depth in his images, watching the lighting angle is instructive.
Lauterwasser's writing draws parallels between these patterns and forms in nature, such as tortoise shells and leaf structures. That is a visual analogy, not evidence of a shared cause, and it is worth saying so when sharing his work.
