We’ve always been revolted and fascinated with the dripping gunk caking the Bryant Park subway station. Why did Mayor Bloomberg, alleged champion of public health, allow the city’s transit system to double as a giant petri dish? How many other stations look like this?

Get real close in the Mars-like gallery above and check back every Friday for a new photo essay. (Photos: Aymann Ismail/ANIMALNewYork)
