        "John Gerrard makes worlds, not pictures. Since the early 2000s his medium has been the real-time game engine, the same software that renders video games, turned to a wholly different purpose: slow, exacting simulations of real sites that run live, in step with the sun and the seasons, with no beginning and no end. The subject underneath nearly all of them is energy, and the power it buys. He arrives in the AB[500] not as a painter trying on a new tool but as an artist who has spent twenty years arguing that the simulation is the native art form of the petroleum century."

        "Gerrard trained as a sculptor (the Ruskin at Oxford, then the School of the Art Institute of Chicago and Trinity College Dublin), and a residency at Ars Electronica in Linz put a team of programmers and a game engine in front of him. His first developed engine work, *One Thousand Year Dawn* (2005), shows a young man on a beach watching a sunrise that the code will take a thousand years to complete. Time becomes a sculptural material. He came to think of the engine as a stage, with the sun as an actor that can be told to rise over ten seconds or ten centuries in a single line of code.",
        "The lineage he names runs through Bruce Nauman and the minimalists: resolved, hermetic objects placed on a platform and left to perform. What follows that first work, the *Smoke Trees*, the *Dust Storms*, the *Grow Finish Units* and the Google *Farms*, are all portraits of industrial systems most people never see. Gerrard insists they are not films. \"This is information,\" he says, \"this is not image, this is not a record.\" You are watching data, rendered frame by frame and discarded, the way the real flows of capital and energy move and vanish."

        "The work that carried Gerrard to the broadest public is *Western Flag (Spindletop, Texas)* (2017), commissioned by Channel 4 for Earth Day. It rebuilds the site of the 1901 Lucas Gusher, the first great American oil strike, now barren, and plants in it a flagpole streaming black smoke: an invisible gas, carbon dioxide, given an image and a banner. Gerrard calls it an invisible sculpture and a flag of mourning for the Anthropocene. It has since stood at Somerset House, in Madrid, in Hamburg, and at Desert X in the Coachella Valley.",
        "Around the same flag idea grew the *Flags* series: simulations of gasoline spreading across the surface of major rivers, the Danube, the Amazon, the Nile, the Yangtze. Working with his programmer Helmut Bressler, Gerrard modelled the iridescent sheen of oil on water with a thin-film refraction algorithm, the same physics that makes a petrol rainbow in a puddle. The result is a beauty he calls a toxic sublimity: the allure of petroleum and its danger held in one image."

Each world runs on the local time of its capital, with its own seasons. It was Gerrard's first WebGL piece, a spatial, temporal world placed directly in the browser, and the first Web3 project in the Art Blocks and Pace Verso collaboration. In 2023, *Petro National #16 (Nigeria)* entered the collection of the Centre Pompidou."

All 195 are generated from a single 112 KB script stored on-chain, using WebGL so the worlds render directly in a phone or a browser, post place, post geography.
