Not sure if this was posted already, but I found an article discussing what the blow-thru floor will look like when finished:

Eventually, the engineers and Gang settled on the blow-through floor, but that raised still another problem: How would the floor look — like a gaping hole or an integral part of the design?


A rendering provided by Gang's firm, Chicago-based Studio Gang, shows that the blow-through floor appears to fit well with Vista's facade, which will consist of horizontal layers that step in and out. The floor will be a "horizontal strata just like the rest of the building," Gang said, adding that she is "very comfortable with the aesthetic."


To further weave the floor into the tower, vertical bands present on the rest of the facade will extend through the floor's exterior. While the floor's perimeter will be open, exposing the elevator core and structural columns to the air, several of the interior elements will be painted black to blend in with the tower during the day. At night, the blow-through floor will be unlit. For safety purposes, a railing will be installed along the facade. The floor isn't expected to be open to the building's residents.
