Description:
A heavily modified version of the beautiful Aurora engine (1.4).  The file below contains both engine and themes (GTK and Metacity) in two separate archives.

Engine installation
First of all, make sure you have installed the GTK+ library development files (libgtk2.0-dev on Debian/Ubuntu, gtk2-devel on Fedora) with your favourite package manager.

Then to compile the Equinox engine, extract the corresponding archive in your home folder. In the new directory, run the following commands:

./configure --prefix=/usr --enable-animation
make

On Fedora 64 bits (and perhaps other distribs), compilation don’t work with the options above. You must run:

./configure --prefix=/usr --libdir=/usr/lib64 --enable-animation

Finally, run this command as root:

make install

Themes installation
To install the themes, extract the content of the other archive in your ~/.themes.
You can easily change the colour used for selected items or tooltips in Appearance preferences.
To fix the issue with the text of selected menu items in Firefox and Thunderbird, copy the userChrome.css in both

~/.mozilla/firefox/xxxxxxxx.default/chrome/ and ~/.thunderbird/xxxxxxxx.default/chrome/

To use the Equinox Evolution theme with Chromium or Google Chrome, open the browser and drag the CRX file (provided in the themes archive) into the address bar. In applications options, don’t forget to enable the display of Metacity borders.

Icon theme
A (still uncomplete) version of Faenza icon theme is now available. Follow the link a the bottom of this page.
