From author's site:

Hyperspace-
This is a real number cruncher of a screensaver. Computers are getting much more powerful these days, and my old savers don't bring them to their knees like they used to. This one does. Of course, you can still turn the settings way down if you have a pathetic, old computer.

Helios-
Throw together some attraction/repulsion particle effects and some smooth implicit surfaces and this is what you get.

Euphoria-
This is about as psychedelic as screensavers get. I thought my Plasma saver was at the top of the scale, but this one is even more nauseating. You'd better find one of those air sickness bags before you stare at this one for too long.
