A giant life-like foggy sunset created at the Tate Modern art gallery in London has received its millionth visitor in just over two months.
About 200 sodium lights help create the effect of a sunset
The work, by Danish-born artist Olafur Eliasson, uses mirrors, light and mist to create the illusion of an amber sun glowing through clouds.
Called The Weather Project, it fills the vast turbine hall of the former central London power station.
But it had led to complaints from staff who said it was making them feel ill.
Some attendants complained that the concoction - made from sugar and water - left them unwell, although an investigation found that the mixture was harmless.
Eliasson's work, based on the British obsession with the weather, involves 300 mirrors on the ceiling and more than 200 lamps behind a semi-circular screen.
Meanwhile, the Tate said it had acquired an important painting by cubist painter Georges Braque.
The Billiard Table, created in 1945, was bought with a £100,000 grant from the National Art Collections Fund.
