La construction du ciel is a video composed of still images and minimal tracking shots. It shows a dysfunctional airport lying idle beneath a blanket of snow; the microscopically slow camera captures icebound runways and parking lots shrouded in fog. The giant airplanes and terminals – symbols of a global culture defined by mobility and networking – are stripped of their function; in the meantime, the sky and fields blur into a spectrum of shades of grey. Now and then, the movie-like image of ’la construction du ciel’ comes close to a white surface, the zero point of unexposed grainy film stock. The video reveals itself to be the construction of a crisis embracing the coordinates of time, place and visibility, which profoundly affects us, entering our bodies and neural pathways via the booming, low-frequency soundtrack (by Oliver Grimm). Later even the noise suddenly breaks off, and a new zero point, that of ‘non-sound’, starts. With the credits that subsequently scroll across the screen, la construction du ciel suggests that a zero point may always also be an acknowledgement of the vacuity of that which has already occurred, and therefore of the irreality of the present.
