Underneath the Sibley dome, adjacent to the College of Architecture, Art and Planning Dean’s Office, is Polyphony. It is an interactive art installation designed by Liu (Leo) Jingyang ’15, Shining (Christina) Sun ’17 and Yue Gu ’16 — all current or former architecture students. To say that the project sounds interesting — “an interactive audio-visual installation that generates a simultaneous feedback loop between performance, image and sound” — is to say little about the installation. Yet, how does it actually look, sound and perform? The first time I entered the John Hartell Gallery (where Polyphony is installed), I sensed that something was wrong.
