At least the blow-thru floor has intentionality to it. It doesn't break the building aesthetically. The seemingly random, splotchy-looking black ventilation (or whatever it is) on the south face of the building, however, is a curse on the Chicago skyline. Tourists will come here and see the blow-thru and be like "okay, sure" but when they look at that ventilation they will be like "wtf"
