Monochrome Monday (mixing metaphore)

I was hoping to think of some appropriate words to complement these images.

Something deep, like the way the ocean and our lives move through cycles.

Better still, something deep and quirky like, "if a black bird falls out of a black sky into the Black Forest would a falling tree in the Amazon harm a butterfly?" 

But that would probably be mixing way too many metaphors and cultures for a Monday.

So then I thought that I was overthinking (again) and decided to let the pix speak (or not) for themselves.
