COSMOCOCA are multisensory environments where people are invited to sit down on cushions, mats or hammocks and become the center of the experience. The environments incorporate sequences of simultaneous slide projections and soundtrack consisted of a montage of music and other sounds. The projected slides made by Hélio show parangolés and other images, as well as album covers, book images and newspapers, on which one can see drawings using cocaine made by Neville. Hélio left written instructions for both public and private performances, with a few variations between them.
