This was an installastion at the Gallery of Modern Art in Oxford. It is called the "House of Books has no Windows". It is a recreation of a house with no windows, obviously, created out of 5000 differnt books. The layout of it and the design behind it is very cool looking. I found books to be such an interesting tool, using them as building blocks almost. It was a created by Janet Cardiff and George Bures Miller, artists from Canada.
