If you’ve never seen a Christmas pyramid before, or sometimes called a Christmas carousel, then here is your first glance. They’re very cool. It’s essentially a scene, usually nativity, that’s set on a rotating platform. There is a rod that goes up through the pyramid and connects to vanes that sit above the scene. Small candles are placed around the edges and lit, and the heat from them makes the vanes turn, which in turn moves the scene. This one is my father-in-law’s. He’s had it for nearly forty years. But you can get your own if you want to spend the money.
