In the picture above, you are looking up at the ceiling of an exterior patio. More specifically, you are looking at 1×1 ipê wood strips attached to medium density overlay board that has been painted black, and a ipê wood trim ring around a light fixture. This is a lot better way to finish out a ceiling over a space you plan on using than paint.
