John Gerrard (born 1974 in Tipperary, Ireland) is best understood as an artist who detached the game engine from its conventional role as a tool for making games and turned it into a medium for sculptures, landscapes, and simulations that continue to operate in real time. He studied sculpture at the Ruskin School of Art, Oxford University, then earned an MFA from the School of the Art Institute of Chicago and an MSc from Trinity College Dublin. After working at Ars Electronica Futurelab in the early 2000s, he developed a practice combining 3D scanning, real-time 3D, and programming. According to his own recollection, he experimented with tools such as Softimage during his Chicago years and later shifted toward collaboration with programmers after Trinity.
A key early work is One Thousand Year Dawn (Marcel) (2005), which constructed a virtual world of a young man by the sea and the sun over an execution time of 1,000 years. Gerrard later described it as his first mature game-engine work. Since then, he has made works on subjects such as the Dust Bowl, industrial pig farming, oil extraction, military exercises, solar power plants, Google data centers, and climate change, presenting them not as recorded footage but as worlds that are being computed in the present.
His work is also characterized by the viewer’s position as an observer of an already running world rather than a player. In SPIRITS (Summer Solstice) (2026), for example, he used a mobile-browser-optimized live-rendered environment and high-resolution Gaussian splatting to transform scanned plastic sandals and shoes into virtual sculptures. Based on the provided context, Gerrard is a central figure in the use of game engines for non-game, environmentally inflected real-time art.
