Icelandic artist Olafur Eliasson used a combination of mirrors and coloured screens to create different abstract scenes for Wayne McGregor's Tree of Codes ballet.
Having previewed in Manchester last year, Wayne McGregor's Tree of Codes production is currently on show at London theatre Sadler's Wells.

The performance is based on, and named after, an artwork in the form of a book by Jonathan Safran Foer, published in 2010.
To create the book, Foer took and cut apart a book by Polish author Bruno Schulz, named The Street of Crocodiles, to create a new narrative.

Jamie xx used an algorithm to turn spaces and shapes from the book into melodies, while McGregor created a dance for each of its 134 pages.
It was the "physical nature" and "vibrancy" of the book that inspired Eliasson's set and lighting designs, which included rows of gramophone-shaped mirrors and screens with circular cutouts.
"To me, books have always been about more than just print on paper," said Eliasson. "Tree of Codes addresses the book as a space that relates to our body."
"I look at the book as vibrant matter. It doesn't explain ideas, but vibrates them. It embodies a space and a narrative ? or various narratives ? within it," he continued. "I tried to translate this feeling into the visual concept."

The show opens in complete darkness. Dancers adorned with star-like lights move around the stage, coming together to form what looks like constella...
