Gjon Mili, a LIFE photographer, came to Picasso in the South of France with pictures of skaters with tiny lights on their skates. Picasso gave him fifteen minutes for one test.
He liked the result enough to give five sessions: about thirty drawings of centaurs, bulls, Greek profiles and his signature. In a dark room he moved a small electric light through the air while two cameras, one from the side and one from the front, kept their shutters open. The drawings vanished as soon as they were made. Some were shown at MoMA in early 1950.
