Arguably, every non-standard set is made for aesthetics (and provides a worse playing experience). If you are a chess player, you are thinking strategy and tactics, and the pieces (at best) blend into the mental background, and (at worst) are a distraction from the game. Which leaves custom sets to the realm of the collector and the enthusiast, people who like to have and think about, but not so much to do.
