On UBUWEB, an archive of shorts by artists including Nam June Paik, Dick Higgins, George Maciunas, Yoko Ono, George Brecht, and John Cale (a screengrab from his ‘Police Car’ is below.)

‘Dating from the sixties and compiled by George Maciunas (1931-1978, founder of Fluxus), this is a document consisting of 37 short films ranging from 10 seconds to 10 minutes in length. These films (some of which were meant to be screened as continuous loops) were shown as part of the events and happenings of the New York avant-garde. Made by the artists listed above, they celebrate the ephemeral humor of the Fluxus movement.’
