All you regular readers of my book and my blog surely recognize what’s going on below?

Yes! A wave field comes in at an angle to the pier and gets reflected, leading to a chequered pattern. And a second wave field comes in with wave crests pretty much parallel to the pier, adding a little more interest to the pattern.

I love watching these kinds of waves! But it is really difficult to take good pictures. Sorry about the over-exposed background…

But it is so beautiful!
