'Supertrees' lightshow in Singapore
The 'supertrees' of Singapore are the central attraction of the Gardens by the Bay, an energy-efficient district of the bustling city state.
During the day, the man-made structures, which mimic real trees, gather energy through solar panels. At night, they come to life and form a spectacular lightshow.
The project, opened in June 2012, was built to highlight the dominant urban landscape of Singapore.
Presenter Mark Beaumont finds out more about the environmental project.
