Bigert & Bergström recently won a competition to create a social sculpture for the new station and community house in Växjö. The piece will be placed in the main indoor plaza. Tree Time is an artificial tree trunk, which have been peeled of its layers to reveal the year rings within the trees. The visitors are invited to sit down and reflect on different time scales: sun time, station time, normal time and the recent newcomer—screen time. Above the visitors’ head, few year rings are “decoupled” from the trunk and rotate on each other, similar to an armillary sphere, which is an astronomical instrument that can be used to measure the positions of the stars and planets on the sky. This instrument becomes an “arborillary sphere” where the four different annual rings will rotate within each other and provide a different formative experience of time.
