Giant Painting Machine
mylar, ink, motors, wood,
Simple switches and a DC motor controller guide the paintbrush across the canvas. The path of the brush is determined by the relationship of the dimensions of the canvas to the speeds of the motors. The speeds of the motors constantly ramp up and down, resulting in curved, rather than straight, lines.
The brushes are filled with acrylic inks in various colors. Mixing decisions are made on the fly, with each wall focused on a certain color.
GPM was first commissioned for a large jewelry fair. We installed four hand-shaped metal detectors that could be used to influence the paths of the paint brushes. When metal jewelry was placed on one of the hands, the corresponding brush changed direction.
The generative sound for GPM was created with a customized, self-modifying version of Larry Polansky's Anna's Music Box software.
