From Free UFO Videos:
This free alien UFO Windows Screensaver is called Aliens UFOs Proof Screensaver because it has Dan Ackroyd's UFO documentary information, and other similar information. The screensavers are tested at AboveTopSecret.com before uploading to Download.com for the public. This alien UFO screensaver has cool sound effects, beautiful music, photos of space, some DVD screenshots we like, an art gallery, and a mention of our friend's Web sites. It is very easy to install and doesn't mess with your PC.
