Amazing Patterns

I couldn't stop admiring these gorgeous patterns on the ice before the snow covered them all on Xmas Eve. Exquisite! I think of neurons in the brain ...

This one reminds me of a line drawn skater with a long scarf trailing along

There were so many patterns like this in my cove - I don't know if it's from something falling onto/into the fragile ice from above, or from differential freezing through cracks and holes due to obstructions beneath!
