Seoul-based light artists Kimchi and Chips install Halo at the local National Museum of Modern and Contemporary Art (MMCA) as part of the institution’s “Multiverse” marathon. In the piece, 99 robotic mirrors follow the Sun’s movement and focus its light into a glistening halo within a cloud of fine water mist. First shown at London’s Somerset House in 2018, the MMCA edition features a new ‘solar farm’ system that uses machine learning for tracking and calibration.
