‘Particles in Space’ is concerned with the energy of movement, of shaping light in darkness, by scratching on the film surface. In this film, Lye focuses on “a smaller, more compact zizz of energy than I’d ever got before on film.”. The rhythms of African drums again provide the musical counterpoint. “I thought ‘Free Radicals’ as an almost unbelievably immense masterpiece and that ‘Particles in Space’ was its contemplative equivalent’ - Stan Brakhage.
