Butterfly Field 3D Screensaver shows a nice cartoonish animation of a nice garden or field with small white flowers, and butterflies of different colors and sizes flying around. There's the sun in the sky, as well as a few white clouds and birds flying around. The screensaver also has background sounds, mainly insects chirping and birds singing, and lovely piano music with several tracks.
Anyhow, if you don't wish to hear the sounds, you can mute them, and you can even add your own music playlist from the settings menu.
In this menu, you will also be able to customize the music playlist. You can shuffle the songs, repeat them, and even play just one random song every time the screensaver starts. Another thing you can customize is the exit conditions. Be careful when you install the screensaver because you may install additional programs like toolbars or other screensavers if you leave those options checked during the setup process.
In short, Butterfly Field 3D Screensaver can help you give life to your screen with a beautiful spring landscape absolutely for free.
