This page simply bounds the wave in a circle. The intention was simply to create an echo for the following page where the shape of the moon takes on the same circle.

I guess there is an implied movement across different scales in this: we could read the 'wave' as essentially small or insignificant, and the moon as big, physical and unmissable. But there is an implied identity to both, since their circumferences will match over these two pages. The idea of 'the insignificant' assuming importance because of its place on the universal scale is a theme of the book; aong with the notion that one never knows quite when circumstances will align.
