Travelers’ initial encounter with ZeitRaum is in the Check In 3 area, where an imposing wall of monitor screens straddles the corridors leading to and through the security checkpoint. A person’s approach triggers a cloud of letters cascading down this wall. Once they come to rest at the bottom, these letters coalesce into texts that, in turn, form the topography of a landscape. Hills and valleys take shape in this way, all of them incessantly in motion because their growth is a function of current arrivals and departures. Every takeoff engenders a hill, every landing a valley.
