The sculpture is a site-specific work which uses the passage of the sun across the sky to trigger sounds which emanate from the sculpture. On the sculptures are sensors which sense sunlight as it hits each part of the sculpture to trigger sound. It fades up from silence in the morning as the sun comes up, then fades out again as the sun goes down. The sounds change according to the seasons. The whole idea of the piece was to record sounds around Brighton for the year prior to the work being completed. They are stored electronically in circuits inside the sculpture and are triggered as the sun comes out and keep playing. It links to different sounds you hear during the seasons, like autumn storms, and people playing on the beach in the summer.

Inscription description

TWINS / This sculpture uses solar energy to change / the volume levels of the sounds which / emanate from it. As the sun moves across / the sky it shines on different surfaces of the / sculpture, triggering music from two internal sound systems. A surface is quiet when in / shadow and louder when in bright sunlight. / Each bronze panel shows a graph on which / the sunshine recordings made at Churchill / Square during the 1997–98 building works. / Similar recordings are taken daily by / weather forecasters across the world. / The graphs have been digitally translated / into music to produce twelve sound pieces, / one for each month of the year. / Each graph charts the sun's trajectory / during the various seasons and the types of / granite used in the sculpture represent the / four seasons. Autumn and Winter form one / 'twin', Spring and Summer the other.
