The Dappled Light of the Sun

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 created a large-scale, immersive work consisting of five cloud-like forms in steel. Made from thousands of tetrahedrons, these forms stand at over six metres high and weigh five tonnes each. Shawcross explains: "The Greeks considered the tetrahedron to represent the very essence of matter. 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."

As well as photography of the works in situ, this publication contains working drawings, structural diagrams and a text by the architecture writer Patrick Sykes.
