Yong Ju Lee’s design, which is based on the firm’s winning entry in the Hangang Art Competition, was facilitated by a computer algorithm that generated the bench’s complex three-dimensional geometry. Based on a ‘reaction-diffusion’ mathematical model, which usually calculates the temporal and spatial rate of diffusion that causes physical substances to spread out over a surface, the algorithm designed the installation’s unique radial fo |
