| The WorldClock Screen Saver displays a high resolution map of the world that will
accommodate even the highest 4K resolution displays. The day and
night areas are clearly shown on the map. You can also have the local time of up to twenty (ten in
the trial version) cities displayed on transparent panels over the map; their times will
be updated every minute. If you choose to display the clock, it will be updated every
The WorldClock Screen Saver can be configured to display the night area using a satellite
composite image of the Earth's surface at night. The day area uses the regular map while
the night area uses this new 'Night Lights' map. These 'Night Lights' are, of course,
night illumination from our major metropolitan areas (street lighting, electric signs, etc.)
which are clearly visible from space.
A typical WorldClock Screen Saver display with the day/night shadow in 'Night Lights' mode is
shown below. This shot has been reduced to fit on this page and some detail has been lost.
To do it full justice, you should see the original image (download the trial and see for
yourself on your computer).
