This installation was first conceived to place the viewer in front of the border between South Korea and North Korea, a space marked by a wide natural border of wildlife, mountains and agricultural fields. The installation recreates of a gigantic territory made out of water, uncrossable but harmless. No-light-zone is a 'no man's land' which induces multiple gazes, conditioned by the distribution of light and the reflections on the surface of the sculpture. The artwork extends flat across a hall of the exhibition space, becomes one with the floor and forms a border. The installation can be readapted for a site-specific purpose, for instance an exhibition space thats has is linked to the materiality of water.
