If the default GTK themes supplied with Ubuntu 11.04 aren’t to your taste ‘Unity Impression‘, a new GTK theme designed specifically with Ubuntu’s Unity interface in mind, is well worth a try out.
Drawing on elements of the impression-ism painting movement of the 19th century throughout, the theme is described by its author, John Baer, as “…falling somewhere between Ambiance and Radiance.”
The theme sports dark scrollbars, inset frames, and sees a smooth almost sandy-coloured gradient used for windows and buttons.
The window controls are small and ‘button free’ A known bug in Unity sees the window controls replaced by a set of defaults when a window is maximised.
