These gestures are the residue on the screen of an iPhone from human touch (the grease of one’s finger). The gestures and twitches are often recognisable according to the app. For example, the swiping left and right of Tinder, and the imprint of stubble from a phone call. Each image derives from a different app, displaying the material remnants of interacting with a virtual window.

Jake Elwes (b. 1993) is a media artist who explores machine learning and artificial intelligence. Their work finds poetry and narrative in these systems' success and failures, their sophistication, and limitations, while investigating their code and ethics. In notable work, the Zizi Project, Elwes exposes AI bias by queering datasets with drag performers, simultaneously demystifying and subverting AI systems.

Elwes lives and works in London, having studied at The Slade School of Fine Art, UCL (2013-17). The artist's work has been exhibited in museums and galleries internationally, including the Victoria and Albert Museum, London; Somerset House, London; ZKM, Karlsruhe, Germany; Today Art Museum, Beijing; Yuz Museum, Shanghai; Pinakothek der Moderne, Munich; Frankfurter Kunstverein; Fotomuseum Winterthur, Switzerland; Honor Fraser Gallery, LA; Fundacion Telefonica Museum, Madrid; Ars Electronica, Austria; Zabludowicz Collection, London; Sculpture in the City, London; Science Gallery Dublin; RMIT Gallery, Melbourne; Onassis Foundation, Athens; Arebyte Gallery, London; E-WERK Freiburg, Germany; Museum für Naturkunde, Berlin; Nature Morte, Delhi, India; Centre for the Future of Intelligence, UK, and they have been featured on TV: ZDF aspekte (Germany) and the BBC Arts (UK).
