Oi Man Estate in black and white by jbarry5

The title simplifies things a bit, as the Oi Man Estate isn't a single building: it's actually a number of identical towers ("houses"), and each tower is made up of dozens of public housing apartments. This image was taken in one of the center courtyards looking straight up on a hazy and overcast summer day. http://flic.kr/p/NprJP4
