Though bland as heck on the outside, golf balls are visual wonders when cut in half. James Friedman admits to not playing golf, but he became fascinated with golf ball cores after cutting one in half. He writes:
Curiosity led me to cut my collection of golf balls in half to see what the cores looked like. To my surprise, what I found inside inspired me to consider that I could discover, in the unlikeliest of places, elegant formal qualities and surprising metaphorical possibilities.
