"Among Brakhage's students were the creators of South Park, Matt Stone and Trey Parker, and he is featured in their student film Cannibal! The Musical. The character Stan in South Park is apparently an homage to Brakhage, in name if nothing else. The opening track of Stereolab's album Dots and Loops, "Brakhage", is also named after him."

"Brakhage's films are usually silent and lack a traditional 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. Most of his work was done in 16 mm film, and 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."
