The following are Macintosh ports of screen savers originally created by Terence M. Welsh, except for Hills, which was created by Nicolas Rouger. In addition, the ports of FieldLines and Helios were based on previous work by UselessSoft the port of Hills was based on previous work by Chris Kent, and the port of Skyrocket was based on previous work by Stéphane Sudre and Jason Sonnenschein. All of these screen savers are licensed under the GNU General Public License; source code is available separately.
All of these screen savers are 3-way universal binaries and will work on PowerPC 32, Intel 32, and Intel 64 (Snow Leopard & later) Macs.
Mountain Lion users: You will most likely need to manually install any given screen saver by dragging it directly into one of the places where the OS expects to find screen savers (/Library/Screen Savers, etc.). In OS X 10.8.0 I haven't had much luck with getting System Preferences to recognize any screen saver that was installed by double-clicking on the screen saver.
FieldLines is a screen saver that simulates the electric field lines emitted by charged particles. In this screen saver, ions move around the screen and bind to the lines of other ions as they get close and unbind as they move away. As the original author has said, physics never looked so good. FieldLines is available in English, French, and Italian.FieldLines requirements:
Helios is a particle attraction/repulsion screen saver where "blobs" emit and receive multi-colored particles. It's difficult to describe, but as some have said about the screen saver, it's pretty insane. Helios is available in English, French, German, and Italian.Helios requirements:
Hills is a screen saver that sends its users on a virtual trip across an endless series of rolling hills, similar to the Palouse region of Washington & Idaho.Hills requirements:
Hyperspace is a screen saver that sends its users on a virtual trip through a wormhole, just like the ones in some sci-fi TV shows and movies. Meanwhile, nebulas and stars fly by. Hyperspace is available in English, French, and German.Hyperspace requirements:
Microcosm is a screen saver that takes users on a trip down a kaleidoscope field of gooey, animated gizmos. Meanwhile, the gizmos fly around and change colors. Microcosm can be configured to either focus on animating a single gizmo, or showing the full kaleidoscope effect.Microcosm requirements:
There's fireworks screen savers, and then there's Skyrocket. Technology has come a long way since the days of the Pyro! screen saver, and Skyrocket shows how far we've come by rendering fireworks in 3D. Oh, and it also has sound effects to go with the fireworks. And unlike some other fireworks screen savers, this one won't change your screen's resolution. Skyrocket is available in English, French, and Japanese.
