I am designing a small amphibious airplane. I would like to show it on a wavey water surface. It would be best to have a glassey surface that is a linear combination of two or three wave systems.

My first try looks OK. This is a boundary surface that has just two sketches that consist of a wavy pattern of circular segments that are tangent ot each other.  The resulting waffle pattern is a bit too regular.

There must be a neat way to make waves in a swimming pool.
