With a body of work that spans painting, sculpture, writing, films, slideshows, and immersive installations, Hélio Oiticica was one of Brazils most original and important postwar artists. At the centre of a generation that developed radical proposals for art and culture, Oiticicas work explores the inherited language of geometric abstraction and reflects on Brazils complex social realities in a time of both accelerated development and limited freedom. The Bólides, which Oiticica began producing in 1963, are experimental and interactive works that demonstrate the artists challenges to the conventions of viewership.
