There are nearly 10,000 bulbs in the exhibition. It’s possible to walk through the square and immerse yourself in the waves of lighting. It also looks pretty spectacular if you can view it from above. There are some superb shots of the show by Paul McGuigan, on the Edinburgh Spotlight website.
The exhibition is free, and is open from 3rd February to 27th April 2014. The lights are switched on from 5pm to midnight each day.
This brief time lapse gives a sense of the way the lights alter the space:
