Architects in Sydney, Australia have found a way to light up a part of the city that was once perpetually dark, hidden from the sun by tall buildings. They've done it by capturing the sunshine, and bouncing it between buildings with an architectural device called a heliostat. Lester Ranby reports.
The video, shot in black and white, was filmed in Los Angeles and directed by Mert & Marcus. It includes a stunning tour de force performance by the Material Girl and her team of dancers and breathtaking visual effects.
