Danish design collective Superflex has filled the Tate Modern's Turbine Hall with a snaking framework of three-seater swings, which it hopes will encourage social interaction between visitors.
The One Two Three Swing! installation features a bright orange framework that weaves throughout the huge Turbine Hall, and continues to the outside of the building.

It was conceived by Superflex as a three-stage journey exploring apathy, production, and movement ? and is arranged across the Hall's sloping entrance, its far-east end, and the bridge on the gallery's first level.
"The work explores the potential of energy generated by social movements, drawing unexpected connections within, between, and beyond institutions, and proposing new uses for urban public space," said the Tate. At the show's "apathy" stage on the sloping entrance, visitors are encouraged to lie down on a 770-square-metre expanse of carpet in a colour scheme inspired by the UK's currency.

Up above, a gently swinging mirrored pendulum is suspended from the ceiling by a 20-metre cable, which is intended to encourage quiet thought and reflection.
In the show's "production" section at the far end of the hall, three-seater swings are made live on-site. Here, each of the swings is assembled and stored before they are distributed across the sprawling orange frame.

The third and final "movement" stage takes place as visitors interact with the assembled swings around and outside...
