Dynamic Stereo Drawing Machine is the latest iteration in Angela Bulloch's major body of work: Drawing Machines (1990–ongoing). The work is an automated machine that draws on a sheet of paper placed on the wall. Two metal rails hold the mechanism that executes the drawing: a longer horizontal and a shorter movable vertical part. The latter one holds a pen that is pulled across the surface of the wall by combining horizontal, vertical, and elliptical movements. A small metal box on the right contains the apparatus that steers the machine.
Bulloch's Drawing Machines are a major theme in the artist's oeuvre. The first one, Blue Horizons, was produced in 1990. Since then, Bulloch has created more than 14 machines drawing in blue, yellow, sepia or red, with varying input mechanisms. The earlier machines were sometimes more directly linked to the viewer's participation: the 1994 Betaville, for example, was activated by visitors sitting down on a bench in front of the work.
This drawing machine is part of a more recent series that executes elliptical lines creating rounded shapes (somewhat reminiscent of human doodling). Like other drawing machines the current work reacts to a particular impulse, but unlike earlier ones, Dynamic Stereo Drawing Machine's input mechanism has been designed to accommodate rounded motions possible. The machine's movements are generated via an integrated internal microphone that respond to a sound impulse.
By using a mechanical process to draw but somewhat arbitrary means to determine its movements, Drawing Machine challenges traditional notions of skill and of authenticity.
