The Way Water Moves

These are clouds painted by Georgia O'Keeffe.   This small canvas, called "Celebration," captures the clouds near Lake George, NY, and in O'Keeffe's imagination. This painting is on display at the Seattle Art Museum. I've been visiting it and buying post cards of it for two years.
These are the inlets and passages of South Puget Sound, north of Olympia, depicted in four USGS topo sheets. The four individual sheets cut up the Sound in an unsatisfying and unhelpful way.  Recently, I trimmed the white borders off each sheet, taped them together (badly),  and thumbtacked them on my kitchen wall. I stepped back and suddenly the pattern ring a bell.
