A survey of artworks acquired by the Nam June Paik Art Center during its COVID-19 pandemic closure opens in Seoul. “On Collecting Time” presents Kim Heecheon, Sunmin Park, Jinah Roh, Sungsil Ryu, and 6 other artists whose collected works are thematically bound in their exploration of “human and machine time in various forms.” Unmake Lab’s Utopian Extraction (2020, image), for example, pairs video demonstrating janky real-time object detection and documentation of slowly evolving landscapes.
