This screensaver shows a beautiful landscape of a city by the beach and a nice sunset over a calm ocean. The ocean water has realistic ripples on it, and you can hear birds singing and ocean sounds, which make the scene much more pleasant and relaxing. Unfortunately, the screensaver doesn't include music and neither can you add your own.
The settings menu includes a small viewer which allows you to see the screensaver's image while you configure the settings. Besides, if you check the "Auto preview" option, you will even see the effects in the previewer, just like in the screensaver. Sadly, there are only a few customization options: you can adjust the animation speed of the water and select the image size. If you want, you can add a transparent analog clock in any of the screen corners, which can help you keep track of time while you are not using the computer.
In short, if you are looking for a beautiful and pleasant scene to decorate your screen with, City Beach Screensaver may be an excellent choice.
