Icicles forming on the plastic above the compost pile by the drain in back:
Water bouncing up and forming a raised edge of ice around a bucket in front, ice on the plastic netting, and the sky becoming blue again.
"Shadows" of objects, where the snow didn't fall. Inside the pan is a curve from the tub above. Under the pan is a place where the snow never fell. And it makes patterns as it melts, too.
