Apple has finally revealed what it intends to do with the glass cube over its Fifth Avenue store in New York City. A photo shows a new sign plastered on the barrier around the store, which is in place while the cube is being replaced. "We're simplifying the Fifth Avenue cube," the message reads. "By using larger, seamless pieces of glass, we're using just 15 panes instead of 90." A diagram shows that each side of the cube will have three vertically-aligned panes.
