MARK TURNER wallows in the virtuosity of Swansea Jazz Festival openers, Simon Spillett and Pete Long

ALGORITHMS have existed since the ancient Greeks and they are increasingly becoming a part of everyday life in the digital age.
We’re not just seeing their practical use in the realm of science, computing and mathematics but also in the arts – particularly in electronic music – and now, as the British Library’s resident artist Michael Takeo Magruder skilfully demonstrates, even in art installations.
Images and metadata from 18th and 19th-century maps of London, Paris, New York and Chicago have been used for the four works on display and, as Magruder explains to me on a guided tour of the free exhibition, the painstaking operation originally involved a bank of one million images of historic urban maps in the British Library’s online digital archive.
