The circle lying in the middle of the ground is not your normal concrete design. Once you sit crisscross applesauce on it, it will begin to spin you around as if you are on a playground roundabout. It will then morph into a flying saucer in space and will take you to anywhere you wish upon. This circle etching in the concrete then becomes your daily transportation to anywhere you wish to go in the universe, which makes working across different planets possible for all of society.
