In this 5-minute film, the second of the Hidden World series, the work of German photographer Alexander Lauterwasser is presented in the context of Cymatics, the study of vibration and its effects on form-making. A brief history of Cymatic research is presented starting with the sound-figure experiments of Ernst Chladni and Hans Jenny. Alexander Lauterwasser is shown continuing the research that Chladni and Jenny began with his custom-built equipment that enables him to produce beautiful geometric patterns in substances ranging from sand to water. The connection of sound to organic patterns in nature and the philosophical implications are also addressed.
