That’s like finding a hidden treasure in plain sight! Subway tiles often have geometric patterns that were meant to give a sense of rhythm, but sometimes people see hidden symbols or maps in them. I’ve seen a few places where the tiles actually encode a route or a historical map. If it looks like a secret map, maybe try drawing it out or asking a local artist – sometimes the old maintenance crews added those for good luck or to honor something. Grab a sketch pad, capture the pattern, and see what story it tells!
