I am interested in the arrangement of fluid molecules of water in 3 dimensional space and the effects of soundwaves on these arrays. I am particularly interested in water, noble gases such as argon and xenon, ionized and tested under different sound frequencies and viewed possibly by micro cymatic devices. It is my theory that sound can be recorded or imprinted on arrays of noble gas atoms if they are dispersed in unusual abundance in a controlled environment. I can discuss the details of my hypothesis with anyone who wants to discuss echoes with me on a theoretical level. Can we find a material or mixture that will show us cymatics on 3 dimensions? Most cymatic devices such as Chladni Plates only show cymatic recording in two dimensions. Your water-drop (micro cymatic) experiments have come closer to what I am looking for in proving that arrangements of units in a fluid environment can be easily manipulated by sound. It my theories are correct, it could be possible to imprint a room with a sound that, with the proper technology, could be reproduced at a later date. We could, with current technology create a cymatic recording using a Chladni Plate and then reproduce specific tones using image recognition software. That would even make a great mobile app. Ok, I might be getting off topic, but that's the way I think and create. "Cymatic Recognition App" or "Cymatic Recording App" you read it here first! :)
