Copenhagen-based designer Eske Rex came to fame with the invention of his ‘drawing machine,’ an elaborate construction powered by weights and pendulums that produces spirograph drawings from ink. Drawing on a Renaissance-age technique, Rex uses this pendulum-controlled drawing device, which is likened to the geometric image production of the 19th-century mechanical apparatus, the harmonograph. Rex investigates the idea of the machine as a sculpture and installation; his pyramidal room-sized drawing structures stand nine feet in height, and in the center of each, a weighted pendulum waits to be powered by hand (an element that prohibits any two drawings to be exactly alike.)
