Split Spiral Spin
1159 x 610 cm base diameter.
Perforated stainless steel and zinc coated mild steel.
Project for a Sculpture as an Interference System. It was commissioned by Warrington Development Corporation for the Birchwood Science Park in 1982.
The sculpture is composed of 8 parabolic vanes, each curving around the preceding one in what appears on plan to be a spiral armed shape. The overlapping parabolic layers of perforated steel create large-scale interference patterns. When back-lit, the sculpture appears transparent, when front-lit, opaque.
