In the summer of 1953, Christopher Strachey, a colleague of Alan Turing at the University of Manchester computer lab, wrote a program that made the lab’s Ferranti Mark 1 mainframe churn out love letters according to a template (e.g., “you are my [adjective] [noun]“). Beginning eight years ago, artist David Link constructed a model of the old computer and started running Strachey’s software (if that’s the word) once more.
