There's a very Eastern (I believe Japanese, primarily) way of thinking towards devoting tons of energy and intense focus on what, at the surface, seems to be a very simple thing. However, the reason for such focus is the pursuit of absolute perfection. This is why you see things like sushi, samurai swords, etc. (very stereotypical, but for a reason) that are extremely stripped down and simple in design, but are crafted to incredible, nearly incomprehensible levels of quality, and within that, *extremely* complex detail.
For an easy way to grasp this concept, watch the Jiro Dreams of Sushi documentary. Literally lifetimes dedicated to a small piece of uncooked fish on top of (nearly) plain rice (with minor garnishes).
This is in contrast to more Western thinking around ornate-ness, detail, elaborate complexity.
Something to think about when considering different artistic styles, whether keycaps or otherwise. Different pursuits of quality.
