Dia Art Foundation has opened a long-term exhibition of works by Brazilian artist Hélio Oiticica at Dia Beacon in New York. The presentation focuses on the artist's formative years from 1958 to 1966, featuring the large-scale installation Grande Núcleo (1960–63). The exhibition highlights Oiticica's transition from two-dimensional painting to participatory, volumetric environments that emphasize spatial awareness and viewer interaction.
