Memé Perlini has created four works in four years (1972-75): Pirandello Chi? (Pirandello Who?); Tarzan; Yellow Whiteness (with sounds of the sea); and Otello (Othello). Perlini works with lights. At the beginning (in Pirandello Chi?), Perlini used small projectors to quickly extract a series of images from the darkness and then immediately replace them with others, in a very rapid montage. He created many views of the same object by alternating the turning on and off of projectors that were placed in different positions. The object was often a performer (for example, a man on a swing was lit by two lights, one above and one below him, that were turned on and off, alternating frenetically).
