As it name suggests, Fall Themed Screensaver is a screensaver that includes images related to that season. It includes four lovely images of trees with falling leaves in different landscapes, like tranquil lakes, rivers, etc. The images appear in order or not, and, what is great is that you can select your favorite ones. You can also select the time they appear on the screen and customize the transition effects. There are multiple effects to choose from, and you can also shrink images to fit screen or enlarge them. Unfortunately, it doesn't include music nor sounds, which would definitely cause a more relaxing effect on the user. Also, you cannot customize the exit conditions, so the presentation ends with any action (mouse movement, keyboard key press, etc.). You will find other options in the settings menu, but they are not applied to this screensaver, so you should avoid them.
In short, Fall Themed Screensaver is a nice screensaver which lacks a few features, but offers four relaxing pictures to enjoy for free.
