The wave curves are made from Glass-fibre Reinforced Concrete (GRC). Units are sized 5m by approx. 2m, and attached to the structure at intervals of 5m. Interior and exterior walls are opposite faces of the same unit. The exterior side is painted with a coating that causes grime to dissolve naturally.
GRC units are made with molds. Cost considerations limited the number of molds that could be made, so the design could use only a limited number of unit variations. Of course adjacent units also had to flow into one another, so that it was not possible to achieve variety by combining any unit with any other.
In order to create diversity and prevent the limited number of variations from falling into monotonous repetition, simulations were carried out using recursive shapes that could be connected when reversed. (A program was planned for this step as well, but could not be finished in time.)

The peripheries of these screens are handled as if cut away.
This indicates that the surfaces continue to expand.
Rectangular segments of these sizes just happened to be cut out of enormous fluid surfaces that continue to expand forever, and the result was these screens. In this sense, there are rules which govern the birth of individual waves, but no rules that govern the whole.
The whole is generated solely from the rules which produce the individual waves. There are parts, but there is no whole.
