The Nations area in Geneva is prestigious and fascinating for many reasons. It is housing almots all the international institutions and is therefore witnessing of a multitude of activities, languages, cultural habits and universal symbols. The several buildings architecture is spectacular and some areas are a tremendous source of visual inspiration. One of these buildings, called "la Maison de la Paix" has strongly impressed me by its architecture and by the institutions it is sheltering. At nightfall, the countless luminous cones reflexions have raised in me the image of a procession of the car headlights on the motorway, during rainfall. I wished in this manner to deliver something of the dense and active atmosphere, through effects of light and material without any human presence, this last one being present after all in the implicit content of the images, with travelling lights as avatars.
