In September 1980, independent film-maker Bill Brand installed a type of linear zoetrope he called the 'Masstransiscope' in an unused subway platform at Myrtle Avenue in Brooklyn, New York. It consisted of a linear wall with 228 slits in the face. Behind each slit was a hand-painted panel. Riders in subways moving past the display saw a motion-picture within. After falling into a state of disrepair, the 'Masstransiscope' was restored in late 2008. Since then, a variety of artists and advertisers have begun to use subway tunnel walls to produce a zoetrope effect when viewed from moving trains.
