The installation required a darkened and insonorized space. Architect Mathias Geoffroy designed a structure for the installation in order to avoid the 'box in a box' situation: two parallel walls, painted in black, on which the speakers are hanged, their sensors protected against direct light. The space between the two walls is open on both sides and can be accessed by the audience, in order to discover Petronella's interactive composition. Sounds are activated when walking and moving on the footboard placed on the floor.
