Frost art?

 
 
It was chilly here this morning — solid ice in the bird bath.  Santa Rosa set a cold temperature record for the date (24 February 2022) of 26°F (-3°C).
 
When I walked out to the car to go to work, I noticed this unusual frost pattern of dots surrounded by circles.  
 
Here's a closer view:
 
 
 

Interesting to see that both components, the center and the rim, were made up of clusters of rectangular crystals.  
 
Here's another even closer view:
 
 
 
Fun!

    Interesting! I don't recall ever having seen a pattern like that on windshield ice before. I wonder what caused it?

    Hi, Alice! Yes, I wonder, too. Maybe there were droplets on the car before the temperature dropped, but I'm not sure why a "moat" effect would develop? There's always something to puzzle over!
