The C-Curve (2007) is a sculpture by Anish Kapoor. During the 2009 Brighton Festival it was exhibited on a specially constructed concrete plinth atop the South Downs chalk hills - near the remote Chattri War Memorial.
The highly polished curves of the stainless steel structure reflect and distort the surroundings.
This "time lapse" / "speeded up" video exaggerates the movement of the clouds.
The video - together with other videos and a number of high quality still images of the sculpture - is also hosted in a flickr collection at flickr.com/photos/dominicspics/sets/72157617853397802/
