Error Code Green Installation in a 430*180* 110 cm corridor, team worked with CHAE DAN. We have a new vision of the green spaces that are becoming "invisible" in the modern city: in the uniformity of concrete and steel, they look like an image that was loaded by mistake during a bug in the system. We have built a 'rest area' for those who are looking for a green space to rest in the future, only occasionally appearing as a wormhole for spatial transition. We find a space — a corridor in the Hongik University campus, with a suspended door at one end, the corridor is so low that only people under 175cm can walk upright through it, and the other end leads to another floor, which is very much how we envisioned the game wormholes.
