　　I'm a creative technologist and the focus of my work is on public installations. One of my driving passions is this idea of exploring nature, and trying to find hidden data within nature. It seems to me that there is this latent potential everywhere, all around us. Everything gives out some kind of data,whether it's sound or smell or vibration. Through my work, I've been trying to find ways to harness and unveil this. And so this basically led me to a subject called cymatics. Now, cymatics is the process of visualizing sound by basically vibrating a medium such as sand or water, as you can see there.

　　So, if we have a quick look at the history of cymatics beginning with the observations of resonance,by Da Vinci, Galileo, the English scientist Robert Hook and then Ernest Chladni. He created an experiment using a metal plate, covering it with sand and then bowing it to create the Chladni patterns that you see here on the right.

　　1:23

　　Moving on from this, the next person to explore this field was a gentleman called Hans Jenny in the 1970s. He actually coined the term cymatics. Then bringing us into the present day is a fellow collaborator of mine and cymatics expert, John Stewart Reed. He's kindly recreated for us the Chladni experiment. What we can see here is the metal sheet, this time connected to a sound driverand being fed by a frequency generator. As the frequencies increase, so do the complexities of the patterns that appear on the plate. As you can see with your own eyes. (Applause)
