Earth 3D Screensaver is a realistic 3D globe model. It emulates a space orbiter window. Our planet looks exactly as it is seen by astronauts. You see the blackness of outer space with sparks of stars on it. You are flying around the Earth, a huge colorful ball with a thin veil of atmosphere. You can use the interactive mode. Instead of moving by a randomly selected orbit, you can control the globe.
Welcome to the chamber of some unknown Medieval explorer and scholar. Old sturdy oak table stands in the middle of the chamber with several heavy dusty volumes on top. One of the manuscripts is open. A map of recently discovered lands lies on the table with a magnifying glass nearby. Most likely, the owner of the room is planning his new trip to the newly discovered lands to describe the people who live there.
