Christmas Decoration Screensaver is a nice screensaver with a Christmas theme. The screensaver includes a huge analog clock with roman numbers and a beautiful Christmas tree with lots of different ornaments and lights. There are also two big red ornaments (balls), which are hanging and rotating the whole time and a message saying "Merry Christmas"in white. The background is red and has shinning stars. Unfortunately, the screensaver doesn't include sounds or music, which would definitely make it much more attractive, especially if there was a beautiful Christmas song.
Another drawback is that it has almost no customization options. The settings menu is very small and it only allows you to customize the screensaver's quality (low, medium, high, best, etc.) and whether you want it to go on a loop or not.
All in all, if you are looking for a simple screensaver with a Christmas theme that includes a clock, Christmas Decoration Screensaver can help you decorate your screen during this holiday completely for free.
