It’s Just a Matter of Time Interactive Tracebox employed software designed to detect the presence of visitors near the object. The software tracked their motion and speed, generating shapes that corresponded to trails of particles. These shapes were projected onto a cube filled with hints of fog. Appearing patterns were influenced not only by the visitors’ movements but also by the density of the fog and the motion of the air inside the cube. To enable this, a fan was installed inside the wooden box beneath the cube. The visibility of the traces varied depending on the observer’s viewpoint.
