Flip & Two Twisters is Shirley Horrocks' documentary about New Zealand-born artist Len Lye. Motion maestro Lye's international reputation rests on his work as a filmmaker and kinetic sculptor, and his lively contributions to the London and New York avant-garde. The documentary explores Lye's career and ideas, with the help of historical footage and excerpts from his films. It includes footage of Lye in typically exuberant form outlining his process, introduces many of his kinetic works, and documents how some of his most ambitious plans are being realised in New Zealand.
