A marble path is set on a pedestal and behind it a TV is placed. If a marble is rolled along the path a miniature camera records live. These sequences are shown on the TV screen. The electric contacts, which are connected to the switch unit inserted into the floor, switch to the corresponding camera. The typical model of a marble path, equipped with electrical power and a video socket: The marble, as ever, is still put in by hand. Immediately the video level mixes with reality. In the right and left axles and, respectively, back- and forward seems to be a crossing of the marble and its image.
