This is the very firs experiment I did in DS10, October 2012. Even if I was unable to find an architectural application, i still find the interference colour patterns to be beautiful images, so I’m posting them here, hoping they will inspire someone else.
Thin-film interference occurs when incident light waves reflected by the upper and lower boundaries of a thin film interfere with one another to form a new wave. Check out the wikepedia article: http://en.wikipedia.org/wiki/Thin-film_interference
Cymatics reveal the geometrical patterns created by vibrating a liquid or a solid with sound waves. In summary it makes sound visible. When a surface is subject to vibrations it distorts in a non uniform way with areas of greater and lesser distorsions.
What Hans Jenny as the founder of Cymatics, pointed out is the resemblance between the shapes and patterns we see around us in physical reality and the shapes and patterns he generated in his investgations.
Jenny was convinced that biological evolution is a result of vibrations, and that their nature determined the ultimate outcome. He speculated that every cell had its own frequency and that a number of cells with the same frequency created a new frequency which was in harmony with the original, which in its turn possibly formed an organ that also created a new frequency in harmony with the two preceding ones.
In the image we see a solid shape created in a vibrating environment. A kaolin paste is heated, it liquefies and is then poured onto a vibrating diaphragm. Wave fields are created during the cooling process. Standing, travelling and interfering waves appear. Once the paste solidifies periodicity is inherent in them, it represents a state of flux. It is steady but has a constant movement within the shape. Within the form everything is in a state of circulation. Periodicity generates and sustains everything.
