Quick overview of how to get Apple's new TV screensavers working on most linux systems.

Using Apple’s Aerial Screensavers on Ubuntu After coming across the [Aerial] ( screensavers for Mac, and installing them, I decided that I had had enough of the graphics-demos of my Ubuntu Precise system. I hope to provide a simple guide on how to add them to your setup as well.

First, you need to install xscreensaver (for example with aptitude, but your distro should have it):

sudo apt-get install xscreensaver

* This is a wrapper class that registers the font awesome .ttf included in the package.
* ControlsFX loads this font dynamically at run time from a CDN. Thus, it works only if Internet
* connection is available
* .
* This class registers an included version of the font. The {@link #init()} method should be called
* during the initialization procedure of the application such that the font is available early.
