The Ptolomeo book towers have recently been given special effects.
As a free-standing book column, 'Ptolomeo Luce' can also hold a large number of books. But instead of just stacking them, the narrow shelf backs the whole thing with a simple strip of light. This light is cleverly directed towards the wall so that the immediate background behind the book tower is indirectly illuminated.
This way the pile of books becomes almost a kind of sculpture, which conjures up a very special flair in your living room.
