Screensaver refers to any animated image or object which is activated on a computer when no one has performed any action on it for a period of time. Normally, any operating system will come with a selection of screensavers which users can select and use. Zodiac Clock 3D Screensaver allows users to see how the ancient people saw the universe millions of years ago. The graphics is based on medieval drawings and illustrations of people who have spent their time studying the universe during that time. The face of the clock stands for the Earth, while a representation is created for the moon orbiting the earth and the sun, which ancient people believed was moving around the Earth. This is made with a semi-transparent outline. The twelve sparkling constellations surrounds the clock, including Aquarius, Capricorn, Sagittarius, Scorpio, Virgo, Libra, Leo, Gemini, Cancer, Taurus, Pisces, and Aries.
Every zodiac corresponds to a specific time frame. Zodiac Clock 3D Screensaver enables highlighting of present zodiac sign and shows the month, day of current week, and date. There is an additional option to add a music track that can change the mood. There is default music included but users can also select from their own private music libraries.
