“Earth Skin” is a work that captures the textures of the ground and buildings through the technique of frottage, expressing them as “the skin of the Earth.” The traces engraved on the surface accumulate the memories of a place, shaped by the intersection of nature and human activity over time. Through these traces, the work explores the relationship between place and people, highlighting the historical and sensory significance of the physical surface. Through the installation, viewers can visually reawaken the memories and changes that once existed in that space, allowing them to perceive the connection between the past and present. The piece symbolically expresses the memories and historical weight embedded in the Earth’s surface.
