Above is a chine collee print. The black and white print was produced by a photo-etching process, and the coloured print was printed digitally on to thin paper and then attached during the printing process.

These images are based on hugely magnified photographs of seed surfaces (photographed with an electron microscope). The purpose and nature of the neural-like appendices is not yet understood, but it is thought that they must interact with their surroundings and receive feedback which determines the future behaviour of the seed.
