"A leading figure in multimedia and technology-based art, Otto Piene was a founder, with Heinz Mack, of the nifluential Dusseldorf-based Group Zero in the late 1950s. This publication highlights the artist's on going exploration of light as an artistic and communicative medium. Piene's Lichtballet (light ballet) performances, first produced using hand-operated lights directed through performated stencils, became mechanized in the 1960s. The artist's light sculptures consisted of motorized lamps, grids, and discs producting a flow of projected light; these machines evolved into kinetic sculptural environments of mechanized effects through the 1960s and '70s. Featuring Piene's own writings on light as an artistic medium, an essay by art historian Michelle Y. Kuo, and an interview with curator Joao Ribas, 'Otto Piene: Lichtballett' documents the artist's pioneering investigation of art and technology."--. book jacket.
