This piece was part of a series of installations by invited artists in a large sandpit in Fabrica Gallery, Brighton, in September 1996.

The installation enlarged and traced layers from an Ordnance Survey map of Brighton, found in the local library. Part of the OS map was missing, and so a gap was left in the sand map. The projected lines of the Ordnance Survey drawing became lines etched out of a temporary surface, a new ground that over the preceding weeks had been reformed again and again by different artists.
