Neon Pictures Free Screensaver is a nice and original screensaver that includes lots of neon glow images. The pictures are cartoonish and involve different themes including music, office, world, sports, and sea, among many others. All the images are shown with a different transition effect, which, unfortunately, you won't be able to customize. Sadly, the screensaver also lacks music and sounds, which would make it much more enjoyable and attractive. I think that at least it should include an option to add your own music.
What you can do, if you want to, is add a 12h or 24 digital clock and FPS counter in one of the screen corners. From the settings menu, you will also be able to customize the video mode, screen brightness, image transition time, and the time the images remain on the screen. There's also a small previewer that allows you to view some of the images included in the screensaver before running it.
All in all, Neon Pictures Free Screensaver is a lovely screensaver that will give life to your screen with an original form of art.
