Though it claims to create professional-style screensavers, this program's finished products actually come closer to the amateur level. The app lets you create customized screensavers from your own images and music, then add a variety of effects. However, since the interface is littered with icons and isn't very direct, we recommend using the wizard.
Though it has almost every tool you'll need to build a screensaver for your own desktop, Screensaver XP doesn't have any features professionals will need. For example, you can't add a license agreement or author information, both of which would be necessary were you to release your creation to the public. Another downside is that the trial version adds a watermark and restricts you to just five images. If you just want to make screensavers for fun, this utility will do the trick, but anyone looking for a professional-caliber solution will need to look elsewhere.
