A transforming public light installation in the city of Fredrikstad consisting of a series of interventions unfolding throughout December 3, 2016. Four mobile industrial light towers were positioned at different locations, in different compositions, along the river Glomma generating reflections in its water. Each intervention had a preprogrammed flash composition. They functioned as temporary beacons indicating through their relation to the previous and current interventions the passage of time and its inextricable relationship to space. The project accentuated characteristics and qualities of the city, simultaneously giving and taking, paying tribute to and challenging the existing.
