“The diagram itself is a cutting of the continuous read out and then a stacking,” he said. Saville explained that the image was the first time the frequency of a pulsar signal was demonstrated, beginning with a research group at Cambridge. ![]() He explained that the band had given him a page from the Cambridge Encyclopaedia of Astronomy (1977 edition, Scientific American notes) and “very astutely spotted this image as potentially a wonderfully enigmatic symbol for a record cover.” The magazine traced the origins of the “computer-generated illustration” to its first publication around 1970.Ī few years ago, the cover was the subject of a four-minute documentary, Data Visualization Reinterpreted: The Story of Joy Division’s “Unknown Pleasures” Album Design, in which graphic designer Peter Saville ruminated on the cover and pulsars (a star that emits repeating series of radio waves similar to a lighthouse beam). The mysterious cover of Joy Division‘s 1979 debut Unknown Pleasures – a black-and-white visualization of pulsar data that looked like digital mountain peaks – is the subject of a new, in-depth Scientific American article.
