Seashells are simply sensational.
They look great, come in thousands of different kinds, are loaded with math, and are kind of weird and strange in a special way that shows you how intense life is. Life happens in so many completely different ways. For instance, your life happens in a soft body held up with hard bones on the inside of you. Hard on the outside, soft on the inside. This is a nautilus, a kind of creature that is spiral- shaped.
