"Transpose 2002" is a sculpture by Michael Dan Archer, located at the junction of Carshalton Road and Langley Park Road, about 250 yards from the town's historic central crossroads. It is 7 metres (23 feet) in height, 1.5 metres (5 feet) in width and 1.5 metres in depth, and made of Chinese granite and stainless steel. It is composed of a steel blade-like structure next to a granite form. The blade contains a grid allowing the sun to shine through on to the granite.
