Now you can feel like an ensign on board the enterprise every time you use your computer.  Make your Mac display LCARS-style backgrounds that move and animate.  Even listen to the ambience of the subtle “blips and bleeps” of the computer.  Now close your eyes and pretend you are on the bridge…

1. Download and install the System47 screen saver by meWho (a newer version is available on MacUpdate, which seemed to work better on Mavericks)

2. Set it as your default screensaver

3. Run this command from Terminal:

/System/Library/Frameworks/ScreenSaver.framework/Resources/ScreenSaverEngine.app/Contents/MacOS/ScreenSaverEngine -background &

This will run the screen saver as a background process, and will replace your background with an animated LCARS display.  You can still use the computer as normal with this running–the perfect blend: Star Trek and OS X.

The screensaver also has audio for that authentic Star Trek bridge ambience.  And it even works great on multiple monitors!

To stop the screensaver, run this command:

kill $(ps aux | grep 'ScreenSaverEngine' | awk '{print $2}')

If your computer is a bit older and slower, this might not be best to run all the time since it will use some of your CPU to run continually in the background.

Have fun and watch out for that Klingon Bird-of-Prey on the starboard bow.

Do this using an app

If you are not a fan of Terminal, take a look at my app!  It will start and stop the live wallpaper for you and will work with any other screensaver.
