Satyajit Sahoo has been working very hard lately to deliver a major redesign for the new and 3.6 compatible version of the fantastic Orion GTK theme.
The chic and modern appearance of Orion is also available for GTK2 application interfaces by using the Murrine engine.
Box-like close and minimize buttons designate the “clear-design” character of Orion
Installing Orion in your system is as easy as putting the contents of the unzipped downloaded file in to /usr/share/themes. If you are using Ubuntu, you can add the corresponding repository by typing the following commands on a terminal:
sudo add-apt-repository ppa:satyajit-happy/themes sudo apt-get update && sudo apt-get install orion-gtk-theme
