Waterfall realistically and physically represents slate, an ancient and natural stone.
The colours, in grey scale, vary from the darkest tone, “dark flow”, to the lightest, “ivory flow”, recalling the natural oxidation process of the stone, a material that is under continuous transformation, changing colour, shape, and structure, and adapting itself to the evolution of natural phenomenon.
