Oh????

When we opened the curtains this morning we couldn't quite understand what was happening with the water feature. It's just a large pot with a solar fountain, this morning it was frozen, and on the top was what looked like an upside down pyramid. I can only assume it was some natural phenomenon caused by the freezing water. It was amazing really.
I've added an extra - on our afternoon walk this dog was desperate to get into the water at the quay.
