From Wikipedia:

Stan Brakhage (January 14, 1933 – March 9, 2003) was an American non-narrative filmmaker. He is regarded as one of the most important experimental filmmakers of the 20th century. He worked with various kinds of celluloid: 16mm, 8mm, 35mm, and IMAX, and was a practitioner of what he referred to as “pure cinema”.

Brakhage’s films are usually silent and lack a story, being more analogous to visual poetry than to prose story-telling. He often referred to them as “visual music” or “moving visual thinking.” His films range in length from just a few seconds to several hours, but most last between two or three minutes and one hour. He frequently hand-painted the film or scratched the image directly into the film emulsion, and sometimes used collage techniques. For Mothlight (1963), for example, he taped moth wings, twigs, and leaves onto clear film and made prints from it. In the 1960s and 1970s especially, his life with his first wife Jane and their five children was frequently shown, though in a fragmented and interior way rather than as documentation.
