Light Painting
The word photography translates as drawing (or writing) with light:
photo = from the Greek phos meaning light
graph = from the Greek graphe meaning writing
Photograms (and Rayographs) are close to pure light drawings because they do not need a camera to generate the image. However, in the early 20th century artists and others began experimenting with long exposures of moving lights in order to create light drawings. Frank Gilbreth attempted to improve the efficiency of office workers by tracking their hand movements using small light bulbs. Man Ray attempted to create what he called 'space writing'. The photographer Gjon Mili captured a famous series of images of Picasso drawing with light. He also experimented with multiple exposures by setting of the flash repeatedly during a long exposure. Contemporary artists like John Hesketh continue to experiment with coloured lights and filters to make extremely complex and exciting images.
