I have had to many e-mails to respond to. So I will try and answer every ones question here. this experiment displays the effects of wave probogation in the audio spectrum. the experiment is done with a chladni plate, variable audio amplifier , and a frequency generator. (although you can substitue the chladni plate with a high powered speaker with a piece of lexan and achieve the same effects.) granuals can be salt, sand or anything. some one pointed out that the shape of the plate has some degree of controle over the shape of the interference patterns. I have not tested this theory yet but i believe it is true. when the observer watches the video the mind becomes overwelmed with information. each band of frequencies seems to have it's own fractal pattern, kind of like and old TV test pattern or a crop circle forming. this clearly displays the nature of energy transference in the audio spectrum. some one pointed out that these patterns are the same as on the walls of Rosslyn Chaple in Scotland. It was the chapel shown in the movie the Davinci Code. Stuart Mitchell (composer and Freemason) noticed that the symbols in the ancient chapel corresponded to those made by distinct vibrations (Musical notes) from that he interpreted an ancient musical piece not heard for centuries.
