Craig Ward
Or if you're a typographer, designer, and photographer with a twisted fascination for germs like Craig Ward, you might want to swab a sample, take it home, put it under a microscope, and snap a picture.
Ward began taking samples of germs from across all 22 New York City subway lines this summer. For each sample, he cultivated the germs into the shape of the train line's name, creating a depiction of the subway system that is both grotesque and captivating.
While his findings may not be 100% accurate given his less-than-precise process, he told us that his results "are true with a degree of certainty."
