Artist Koh hon scratches cold aluminum repeatedly and captures shining light. He represents the essence and cross-section of the world by describing the human body, nature, cities, and the universe. Scratches engraved on a solid aluminum glow brilliantly with rhythmic effects like a hologram depending on the light and the viewer’s angle. The cold metal makes us feel complex and deep emotions. With the philosophy that ‘Everything that exists in the world moves’, he focused on the contrast of the cold metal and the dazzling light.
