I’m guessing this will most likely take most people by surprise… well it did me, anyway =) That sound can form geometric patterns just seems so logical and elegant, yet at the same time I would’ve never thought it possible. It’s extremely interesting to me that it seems there’s an abundance of coherent phenomena, similar patterns appearing in a lot of areas where you just wouldn’t expect them to. Ancient greek philosophers were the first to  discover (or at least claim) that maths are a universally true language of the universe, and somehow, I feel that cymatics connects to that ancient assertion in an interesting way.
