For one night only, LUMINEX: Dialogues of Light will turn five blocks of Downtown L.A. into a walkable exhibition of digital artwork. Curated by the NOW Art Foundation, the April 10 event features site-specific works from seven artists, including Refik Anadol, who designed the Walt Disney Concert Hall’s centennial celebration projections, and the Art Department, the anonymous collective behind the short-lived Griffith Park Teahouse and 2019’s surreal dandelion factory.
