QStars is a screen saver made with Qt technology.
In order to use QStars, you'll need to have Qt 3.x installed on your computer. Once you have that squared away, installation is a breeze. Simply run the following commands: qmake, make, and make install. Once you're up and running, you can access a variety of options and controls.
To learn more about QStars and its options, you can use the -help command. If you want to set up the screen saver or run it in a specified XWindow, you can use -setup or -window-id wid respectively. Additionally, it's possible to run the screensaver in demo mode with the -demo command.
If you do opt to run in demo mode, you'll be able to control the speed using the UP and DOWN arrow keys. If you want to switch up the scene, select RIGHT, and to exit the screensaver altogether simply hit Q.
Overall, QStars is quite impressive. The latest release includes support for asteroids and sprites for them, as well as keyboard support (for the demo mode only). It's clear that the development team has put a lot of effort into making QStars as immersive and enjoyable as possible. If you're looking for a screensaver that's out of this world, give QStars a try.
