Gizmo
While working on the Gizmo I noticed that the Sun doesn't always appear in the south or north poles. The sun causes our seasons, winter, spring, fall, and summer, due to the tilt of our earth. The southern hemisphere in the summer for us, is really Winter to them. In the winter for us it is summer down there. Why? Because they have more direct sunlight in the winter that we have. people at first thought it was the distance between earth and the sun. The way earth revolves around the sun is kind of oval like. During fall, it is spring in the Southern hemisphere if you are in the Northern hemisphere.
