A design for a reed bed in the pattern of a double vortex taken from a cross section of the human heart. The proposed reed bed is for Lewes Railway Land Wildlife nature reserve and was designed in collaboration with the Railway Land Wildlife Trust to up the biodiversity of the reserve. It will be seen in its entirety from the adjoining hill, on the ground it will be virtually invisible. Funds for construction are being sought and the work should be up and running by 2003.
