This room further contains a "sound tunnel" which the visitor has to cross when entering the first of the three rooms, "sound warp". The light object of this room entitled "Fruits of Columbus" has been conceived and realized by Hens Breet.

By crossing room 3 and room 4, you get to the room exhibiting "lines between", with a light object by Werner Cee.

This room takes the visitor back to the hall, where he will turn to the right and enter the third space of sound and light: "Lost". Werner Cee has conceived a special motor-driven light installation for this room.
