From the Catalogue:
Famously featured in Stanley Kubrick’s film A Clockwork Orange (1971), The Rocking Machine is a Medicom Toy, Tokyo reproduction of the original edition of six designed by Herman Makkink in 1969. Makkink described this comic kinetic piece: “Pop Art was in full swing and so was the sexual revolution, so I combined a penis with a beautifully shaped female rear in fibre glass. I thought this would be really shocking. I thought I could make the object move by constructing a heavy pendulum swing inside. To my surprise I found that it made an irregular movement, so I exaggerated that by adding extra weights in various places. That resulted in Rocking Machine's specific, jerky motion" (Herman Makkink, © 2000 Drencrom V.O.F.).
