'Oil Stick Work (Angelo Martinez, Richfield, Kansas) 2008' — by John Gerrard

The 35-year-old Dublin-born artist, who now works in Vienna, is currently showing a piece entitled "Animated Scene" at the 53rd Venice Bienniale, one of 44 "collateral events" alongside the official roster of 100 or so projects.

Gerrard's show consists of three recent works using large-scale projections in a boathouse on the former monastery island of Certosa.

The caption for the video up top: "'Oil Stick Work (Angelo Martinez, Richfield, Kansas) 2008' is a virtual sculpture depicting a solitary aluminum corn silo on the austere landscape of the American Great Plains. At daybreak, in real time, a Mexican-American builder named Angelo Martinez arrives at the silo and carefully paints a small black square on the exterior of the structure with an oil stick crayon. Within thirty years, working a six-day week from dawn to dusk, the building will be entirely covered and transformed into a dark, negative object on the landscape. In 2038 the Martinez character will complete his task and leave the scene."
