Visual poem - The Foghorn

I created this in Image Chief from this poem published a few weeks back:

I hear three moaning foghorns tonight,
Probably at Bainbridge Island,
Point No Point, and Alki.

I can't detect a pattern.
The foghorns sing to each other
Back and forth across the murky Puget Sound. . .

There will come a time
When we will likewise
All sing to each other.
