Love that ceilings don't need to be ignored. The box pattern is so classic and crisp. They pose some problems that need to be thought out before installation, but can look amazing if processed well.
Also, I love the industrial lights in their own right, but also how they butch the room up a bit. These would be great in an Urban Nautical or Industrial Casual house. Yes, Industrial Casual is my new phrase. Or until I think of a better name for it.
