The "Wall Tour" opened at the Los Angeles Memorial Sports Arena on 7 February 1980. As the band played, a wall of cardboard bricks was gradually built between them and the audience. Several characters were realised as giant inflatables, including a pig, replete with a crossed hammers logo. Scarfe was employed to produce a series of animations to be projected onto the wall. At his London studio, he employed a team of 40 animators to create nightmarish visions of the future, including a dove of peace, a schoolmaster, and Pink's mother.
