A cellular automaton, mathematically, is a set of very simple rules which can be used to generate a pattern. Among these entities lives Rule 30, which incredibly, despite such simple rules, creates a pattern that is mesmerizing and complex. Even more amazingly, the (biological) pigmentation cells of certain seashells implement this rule, so that those shells are covered in the same bizarre & beautiful pattern.
That such a wonder arises from simple mathematics, and moreover that it appears in nature, is figuratively emblematic of the OneStone brand, and now literally so emblematic in this snapback hat.
