be lust, it wouldn't be just clean." She complemented saying she mentioned that the video should be "white" and "frozen", and then it "melts because of love" and "making love". When Cunningham first heard the track, he wrote down the words "milk", "sexual", "surgery", and "white porcelain"; they outline what would become the music video. Concerning this, Cunningham added that it was like Kama Sutra meeting Industrial Robotics and that because of the surreal nature of the images, they could be "sexually suggestive" as they liked. Initially, it was planned that during the visual's ending, the robots would unfold like a flower as they mated, revealing an abstract life form made from the two artificial forms. However, the team could not manage to materialise this thought. The robots were designed by Cunningham and were built in full-size by Paul Catling—who had also sculpted the masks for Aphex Twin's "Windowlicker" (1999)—in clay in two hours. He also worked with Julian Caldow in set design, which was created by Chris Oddy. The treatment described the set as an "elegant" and "white environment" with "a Japanese feel to it". However, the music video's director was dissatisfied with the result and relied heavily on post-production. On the shoot there were two main robot arms, but during its post production, a third and fourth robot arm were created in computer-generated imagery. The video was shot at Bray Studios and Greenford Studios, and post-production was handled by Glasswork using the software programs Softimage and Flame. Cunningham said that every shot in the clip had four layers. He reportedly first shot the set and the props doing nothing for about 21 seconds, and then removed the robot and replaced it with Björk, who had her face painted white and wore a blue suit. Using a mix of the master shot and a live feed of Björk in frame, the production team tried to match up her face and the robot body as much as possible. Only Björk's eyes and mouth were used, with the rest of the robot representing 3D animation traced from her real head. Cunningham has described the filming process as an unpleasant experience: Björk left Cunningham alone to work for the video, refusing to see the product until it was finished, explaining that "when you come across someone as special as Chris you just go humble", which Cunningham said made the work much easier.
