Behind all the tarps the box is also all closed in now, other than some of the glass and cladding on the stairs themselves. And the fourth and fifth floors have been turned over to the AGO for tenant outfit. A lot of tenant work has already been done through the rest of the building too, light fixtures and doors and tiling and such.
The earthquake motif of the titanium panels has been carried through much of the rest of the building, like the granite used in the main entrance, the concrete floors in the tower (yes, start complaining now, the addition has finished concrete floors), and even the wall tiles in the bathrooms. The stacked-box (for lack of a better term) motif also gets heavy play.
edit: And you can only just make it out on the webcam, but the steel for the glass lip at the bottom of the Galleria is going up.
