Waveform is a system of curvilinear shelves that represent the undulating waves of the sea. When viewed from the side, the first thing you notice is this effect. Then slowly the function reveals itself as you become more perpendicular to the shelves. Each blade is a unique shape with progressively change form from right to left and top to bottom creating a three dimensional waveform especially visible from the side. These could be sold individual or as a set.
