Extending his experiments in the technique of ‘direct film’—creating films without a camera by directly manipulating the filmstrip—Len Lye created Particles in Space in the last year of his life. Each frame of the black-and-white sequence was scratched into the celluloid to form a rhythmic, almost meditative abstract work that suggests the realms of physics or astronomy. Flecks of white dance around the screen, sometimes cohering into more definite shapes like stripes or forming frameworks that seem to rotate in three dimensions. The particle formations correspond to the changing pulses of drumming tracks from the Bahamas and Nigeria, as well as sounds recorded from the artist’s own metal sculptures.
