Seoul-based light art studio Kimchi and Chips launches Another Moon into the skies over Zeche Zollverein, a former coal mine turned World Heritage Site in Essen, Germany. Premiering as part of NEW NOW festival in celebration of the end of fossil fuels, the installation’s ring of 40 solar-powered laser projectors captures sunlight during the day to cast it back into the sky at night. Where the beams meet, a 3D sphere—another moon—appears.
