The sculptures of Conrad Shawcross RA explore subjects that lie on the borders of geometry and philosophy, physics and metaphysics. For the 2015 Summer Exhibition’s Annenberg Courtyard installation, Shawcross has created a large-scale, immersive work consisting of five steel, cloud-like forms. These are made from thousands of tetrahedrons and stand at over six metres high and weigh five tonnes each.

“The Greeks considered the tetrahedron to represent the very essence of matter,” Shawcross says. “In this huge work I have taken this form as my ‘brick’, growing these chaotic, diverging forms that will float above the heads of visitors who will be able to wander beneath them.”

A paperback book entitled ‘The Dappled Light of the Sun’ will be published in June 2015. It includes photography of the works in situ as well as working drawings, structural diagrams and a text by the architecture writer Patrick Sykes. RA Publications, £9.95

The Summer Exhibition 2015 is in the Main Galleries from 8 June — 16 August 2015.
