This application hands out some rather sagacious desktop enhancements free of charge, though it's only for XP users. PowerToys Fun Pack has two installers, one that allows you to play your favorite videos as a screensaver and another that automatically changes your wallpaper images. The video screensaver's practical interface is configurable via the Windows display properties window. You'll simply go to the screensaver options and select XP Video PowerToy to access its features. You can set your video file to play continuously, mute the sound, and determine the screen size and playback speed. The wallpaper changer's customary interface allows you to select various image files to randomly shift from one wallpaper to the next as often as every 15 minutes or as sparingly as once a week. It also can be set to display full-screen slide shows from the system-tray icon. Anyone keen on propagating a little desktop variety will enjoy PowerToys Fun Pack.
