We have all these murals at street level, and all of these crowns as just plainly lit surfaces (aside from City Center's led displays). Does any city have a skyscraper with its crown covered in a mural?
At minimum if they wanted to black spandrel the whole thing, they could have at least done a bare minimum...kept the angular thing going...and mounted a large scale diagrid of thin LED light bars over the spandrel to do something. Surely they could have found a few dollars from somewhere else in the project to shift up there.
