Orion: A New, Clear GTK 2/3 Theme

Orion is a new, clear GTK3 theme created by Satya, who’s also behind other beautiful GTK and GNOME Shell / Cinnamon themes like Evolve, Shine, Minty, Ambiance Blue and others.

The GTK3 theme is powered by the Unico GTK3 engine, comes with a modified Boomerang Metacity theme and is compatible with GTK 3.2 (both GNOME Shell and Unity). Orion also includes a GTK2 theme, for compatibility with GTK2 applications.
