This scale-like pattern seems to be an innovation, with morning sun tinging portions with gold. The scale pattern can be seen as a miniature version of the backward "L"'s in the image above.
The artist-in-residence is content with its humble dwelling, needing nothing more than an occasional rain to keep it full.
Those flat spaces between the crystalline lines are open water, and the whole pattern could be rotated in the bowl without breaking it.
Sunlight and rotation of the photo made for a jazzy effect.
Leaves collecting in the tub hint at collage or mixed media, and may add a subtle tinting to the water over time.
An hour later, the crystals had melted away, leaving open water. Thanks goes to Leo, our dog, for getting me out in the backyard first thing in the morning.
