Free Radicals is a black-and-white animated film short by avant-garde filmmaker Len Lye.[1] Begun in 1958 and completed in 1979, Lye made the film by directly scratching the film stock. The resulting "figures of motion" are set to music by the Baguirmi tribe of Africa.[2]
In Experimental Animation: the origins of a new art, Len Lye recalled making Free Radicals:
"I made Free Radicals from 16mm black film leader, which you can get from DuPont. I took a graver, various kinds of needles. (My range included arrowheads for romanticism.) You stick down the sides with scotch tape and you get to work with scratching the stuff out. … … You hold your hand at the right height and act is if you were making your signature. It goes on forever. You can carry a pictographic design in your head and make a little design. You can't see what you're doing because your hand is in the way. That's why those things have that kind of spastic look."[3]
Free Radicals screened in 1958 at the second .[4] It was released on DVD as part of Rhythms, a collection of short films by Lye.[5]
In 2008, the film was included in the annual selection of 25 motion pictures added to the National Film Registry of the Library of Congress being deemed "culturally, historically, or aesthetically significant" and recommended for preservation.[6] [7]
