3D Earth Screensaver is more than just a standard screensaver with some nice space imagery.

This screensaver makes you feel like you're flying through space. It presents you with an animated image of our planet as it floats in outer space, including also the Sun, the Moon and even the ISS orbiting around. Images are really beautiful: you can see reflections from sun beams on the surface of Earth, and also the city lights that begin to appear as darkness covers the planet.

3D Earth Screensaver includes two viewing modes: the demo mode, which simply acts as a screensaver and displays images, and the interactive mode, which enables you to actually interact with the screensaver. You can move from one point to another, zoom in or zoom out and learn more about our planet thanks to the screensaver's layers that include time zones, flags, borders and other details. Just one thing: don't expect to reach street level. This is not Google Earth.

On the downside, I didn't like having icons and text boxes displayed on the image in demo mode. I would have preferred to just have the gorgeous image of our blueish home: Earth.

It may not be as accurate as Google Earth, but 3D Earth Screensaver delivers beautiful images of our planet while you're away from your computer.
