gtk2-engines-spherecrystal 0.7-14 (i386 binary) in ubuntu gutsy

 This is the Spheres and Crystals theme for GTK+, Nautilus and
 Metacity, which aims at providing a unified, blue Gnome desktop
 with an aquatic design, using icons from the BlueSphere, Connectiva
 Crystal and Gorilla metathemes. Its look also integrates with
 the KDE Liquid theme.
 .
 Most of the icons are in the scalable SVG format, providing a fast,
 high quality rendering, especially on large displays.
