From Nick Zitzmann:
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.
What's new in this version:
Brought the Mac port up to date with the Windows version.
The nebula and wormhole can now be enabled and disabled.
