In 1980, artist Bill Brand installed an animated mural that's viewable from a moving subway train in Brooklyn, New York City. Titled Masstransiscope, the artwork is basically a giant zoetrope - an optical toy popular in the Victorian era, where a series of still images shown through slits on a rotating cylinder produce a rough animation.
Brand and a team of artists painted a 300-foot long mural consisting of 228 hand-painted panels in self-contained units illuminated by fluorescent lights. Subway passengers on the B and Q lines looking out the window between the Dekalb station and the Manhattan bridge will see an animated image as the train moves past the panels.
Masstransiscope fell into disrepair, but Brand and the Metropolitan Transit Authority decided to restore the artwork in 2012.
