Presented at the Yokohama Triennale 2020, this project consists of performances in public space and an installation. The work began after Tan observed a man in Shibuya ringing a bicycle bell by hand to move through a dense crowd. Intrigued by this improvised gesture—an object meant for motion, used while standing still—Tan reworked the idea into a handheld bell mounted on a dead twig. During the COVID period, he performed with it in streets of varying crowdedness, testing the tension between calling attention and asking for distance. The installation extends this study into an architectural setting: a living tree planted beneath a circular concrete opening, its branches reaching upward. Multiple bicycle bells are tied to the branches with red strings, allowing visitors to tug and ring them. If the handheld bell explored temporal movement among pedestrians, the tree installation introduces a quieter, almost spiritual resonance—echoing the Shinto practice of ringing a bell to announce one’s presence.
