Interface (A point where interaction occurs between two systems—processes) The motivation behind this picture came from the possibility of the impeding rise in the sea level and it’s effect on both the works of man and also the ancient land .In the scene, the incoming tide (which represents the future) washes around the base of the figure of Uenuku (which is representative of the primordial world). The present is the area of conflict - the shoreline. All of this is presided over by the ambiguously shaped and time sculptured curves of the hills and brooding sky. The underlying idea is that permanence is really a matter of degree. Change happens at the interface between past and future, sea and land, human cause and effect.
