This is a serious work of art and not bad science either. This guy made this orrery, a physical model of our solar system. Awesome. I want one! He used nice stones for each of the planets and tried to match the colors. The gears are also beautiful works of art and the model actually works. Each crank of the handle at the bottom right represents a certain amount of time and the planets move accordingly. Excellent work! Read more about it here ...
