If you are tired of the usual screensavers with 2D images or graphic effects that aren't complicated to accomplish, try Green Fields 3D Screensaver. If this screensaver creates the surprising effect of flying very low over an endless field that is covered with green grass. With the blue sky and blinding light (specially if we look at the Sun) it is a really relaxing field and that is very well designed.
What's more, if we have the speakers connected we can listen to a soundtrack that is specially chosen for the occasion, perfect to relax and stare into infinity for a couple of minutes. What's more, in the configuration panel we will be able to see all the options so that everything works like it should, from the resolution to the way to close the screensaver.
