These screen savers have been written for Windows 95/98, but they should also work on NT 4.0 and up (However NT 5.0 / Windows 2000 is required for the Direct X ones).
Your desktop needs to be running in at least 256 colour mode, (but 16 bit colour will give the best compromise of speed vs. visual appearance) and the meatier your processor the more stuff you will be able to get running at once.
This features 4 different types of 'popular' UFO designs, all rendered photo-realistically, which spin or wobble their way around your screen. More designs will be added as and when time permits.
Requires Direct X version 5 or greater

This also uses the Direct X engine, and is heavily inspired by the opening credits of Tim Burton's Mars Attacks! film. It features swarms of saucers in gently wobbling formation, parallax-scrolling up the screen.

Yet another spinning screen saver - (do I detect a theme here?). The Lament Configuration Puzzlebox from the Hellraiser films.
