Sky Mirror, which measures 10 metres in diameter, has been placed on the side of a lake where a Henry Moore sculpture once sat.

These are just some of the reactions I overheard from visitors to "Sky Mirror," left, by the British sculptor Anish Kapoor.

Sky Mirror is a public sculpture by artist Anish Kapoor.

Sky Mirror is a six-metre-wide concave dish of polished stainless steel weighing ten tonnes and angled up towards the sky.

It took six years from the initial idea for a major new piece of public art to the unveiling of Sky Mirror on 27 April 2001, and cost £900,000.

Most recently, Sky Mirror has been installed in Brighton's Pavilion Gardens for the Brighton Festival.

A version of the Sky Mirror also exists in the Hermitage museum in St. Petersburg, Russia.

From 28 September 2010, Sky Mirror and three other Kapoor sculptures were exhibited in Kensington Gardens, London.

Sky Mirror is currently showing at 'The Museum of Contemporary Art" in Sydney, Australia.

In 2001, Sky Mirror, a large mirror piece that reflects the sky and surroundings, was commissioned for a site outside the Nottingham Playhouse.
