John Cayley is a writer, theorist, and pioneering maker of language art in networked and programmable media. Apart from more or less conventional poetry and translation (Ink Bamboo, Agenda, 1996 and Image Generation, Veer, 2015), he has explored dynamic and ambient poetics, text generation, transliteral morphing, aestheticized vectors of reading, and transactive synthetic language. One of his recent works is a skill, The Listeners, for a well-known digital assistant. He now composes as much for reading in aurality as in visuality, and investigates the ontology of language in the context of philosophically informed practice-based research. Professor of Literary Arts at Brown University, Cayley co-directs a graduate MFA track in Digital & Cross-disciplinary language arts. Selected essays are published in Grammalepsy (Bloomsbury, 2018, made available in Open Access here). EBR first published Cayley's hypertext essay 'Why did people make things like this' in 1997 and he has made contributions intermittently ever since, including the influential 'The code is not the text (unless it is the text)', and 'Base resonance' (on Saul Bass), 'Aurature at the end(s) of electronic literature', and 'Grammalepsy: an introduction'.
