I have recently curated the exhibition Flow which explored the ways in which the physical materials that artists choose and use to create work influence and direct the final outcome. It examined the tension created between the intention of the artist and the potential of accident. Flow included painting, photography, film, ceramics and installation by Alexis Harding, Solveig Settemsdal, Harriet Hill, Jonathan Keep, Clare Price and myself. See http://www.oldbigschoolgallery.co.uk/past-exhibitions/flow for the film and catalogue.
