I’m working on an atomic model for quartz at the moment. It is one of the constituents of the clay that lies beneath the hospital. Quartz has a very regular structure that could repeat for ever, which makes the edges interesting. What to do here? How to break the pattern? I have made the centre of the sphere scientifically accurate, the edges aesthetically accurate. Sculpting with atomic model kits is something I want to explore further. They make you work in prescribed ways – collaboration with a dancer?
