A cascading Harry Bertoia sculpture falls from the oculus of one building constructed by this architect, which contains an aluminum spire atop a windowless brick cylinder surrounded by a moat. He placed a green "oval" between that structure and a nearby auditorium that he also designed. He designed a thin-shell roof over a "head house" in a structure that used red carpet in tube-shaped departure-arrival corridors.
