]]>While I'm not affilated with the Ubuntu Unity Team, I am a satisfied user of this desktop environment and its Ubuntu flavor (which recently became a official Ubuntu flavor over a month ago).
Recently, Rudra Saraswat and his Ubuntu Unity team has started an unofficial repository which made it possible to install Unity on arch (for the first time since 6 years ago when Unity-For-Arch was abandoned). I believe it should included in the official arch repository and be quickly installed on Arch Linux, just as you would with GNOME, KDE, Cinnamon, etc.
