"Quantum Cloud" is a 30 metre high x 16 metre wide x 10 metre deep elliptical cloud sculpture which stands on four cast iron caissons in the River Thames adjacent to the Millennium Dome. It is the work of "Angel of the North" sculptor, Antony Gormley and is formed from 1.5 metre long lengths of randomly oriented steel sections which diffuse at the edges and condense into a 20 metre high human body form at the centre. Prior to the erection of the B of the Bang sculpture in 2005 it was the tallest sculpture in the UK.
The engineering design team of Elliott Wood Partnership and FEA Ltd worked closely with the sculptor to develop the full scale realisation of his vision for the client, the New Millennium Experience Company. Fractal growth software written by FEA was used to develop the structural form, and LUSAS finite element analysis modelled and analysed the unique structure.
