WOW! Watching sound mess with the physical world (or at least that which we can see) never fails to impress! New York musician, and let's face it absolute bloomin' genius, Nigel Stanford teamed up with with director Shahir Dua to bring you this video called 'Cymatics: Science vs Music'.
Cymatics is the science of visualizing audio frequencies and Stanford says he was inspired to make the vid after hearing about the neurological condition synesthesia - where senses are represented differently in the brain.
You can see how the videos were made on Stanford's website here.
