Christmas beauty of the day.
I don't remember what this is called, but it was the last Christmas present son Peter bought for us.
I believe it is Scandinavian in origin, or perhapsl German. It certainly isn't Appalachian.
When the candles are lit on the bottom, it creates some sort of effect that makes the blades twirl on top, thus making the other levels rotate, too.
UPDATE: It's called a German Christmas story pyramid. On Amazon, they're selling for about $800!
