Painting with light at the Wolsfon Institute, Durham University. A study of the natural fall of light in the main atrium space led to the development of a series of ‘Prismatic Light Shelves’ that reflect and refract light patterns beyond the natural fall of light. Staff and students witness the space transformed by projected light and colour. I am currently developing a range of light shelves which reflect and refract light in various ways adding texture, colour and movement. Discretely located, building users see the only the light projections, which will change over the forthcoming weeks and months. Their responses to the changes are being invited and recorded.
