Hélio Oiticica was a Brazilian visual artist, sculptor, painter, performance artist, and theorist best known for his participation in the Neo-Concrete Movement, for his innovative use of color, and for what he later termed "environmental art," which included Parangolés and Penetrables, like the famous Tropicália.
