“3D print embodied by the mouse movements of its own purchasing”, inspired by Robert Morris’ “Box with the Sound of Its Own Making” (1961) as well as by the change of the mode of production since then, is a 3D print whose shape was determined by the artist’s mouse movements on an online 3D printing & shopping website. As the artist enters the site and navigates through the shopping menu before there is anything to order, a custom software tracks the mouse movements and visualizes them as a 3D shape. This way, the attempt to shop for a 3D print becomes the very gesture that forms the object to be purchased.
