The screensaver is configurable. You can play with many of its parameters: enable or disable music, sound effects, use DirectX for faster animation, stretch the image, set the order in which the images will be displayed and time intervals over which they'll change. There is an option to let you display the clock as the screensaver runs and you can choose the desktop position for it. By default the screensaver plays its own melody but you can set your own music to be played during the screensaver playback. Any picture from the screensaver can be previewed in the thumbnail mode and set as the desktop wallpaper.
