Free USA Flag is a simple but nice screensaver which shows the United States' national flag waving gently in the wind. The flag occupies the whole screen and it is shown very closely. Unfortunately, the screensaver doesn't include sounds or music, which would definitely make it even more enjoyable and exciting. It would be great if you could at least add your own music or if it included the national anthem.
Sadly, there are also no customization options, since the settings menu is actually more like an "About" window than a configuration menu. You will see the option "Mute sounds", but not even that option is available in this screensaver.
There are two versions of the screensaver: high-definition and standard-definition. This one is the high-definition version, which offers better graphics; but if you want the other one, you can get it from the developer's website provided.
In short, if you are patriot and you are looking for a simple screensaver with the American flag to decorate your screen, Free USA Flag 3D Screensaver may work for you.
