Sky Art is the genre pioneered by the German artist Otto Piene - co-founder of the ZERO group and, from 1974, director of MIT's Center for Advanced Visual Studies - who began developing it around 1968 and named it the following year. Taking the open sky as his canvas, Piene drew giant arcs, rainbows, flowers, and figures in the air with translucent helium balloons and lasers, staging them as communal 'Sky Events' that lifted art out of the gallery and across a whole skyline. The practice grew out of ZERO's experiments with light and air and out of Piene's smoke and light works; landmark moments include the Sky Art portfolio of 25 lithographs made at the Tamarind Lithography Workshop (1969), the Olympic Rainbow floated over the Munich Olympic lake at the 1972 closing ceremony, and the inflatable performances he staged with collaborators such as the cellist Charlotte Moorman.
