I didnt find any theme that fitted my taste, so i modified some of the available themes and made a pack of it.. Hope someone likes the classic platinum look as much as i do.
To get the global menu you must install the gnome panel applet for that particular function.
Main package includes GTK+Metacity+Cursors+Font+Wallpaper
But i have also added an GDM theme as stand alone download. (available as the second link.
ALSO: This pack is as far as i know this is only for manual install... Might wotk, but i havent tested the automated sollutions.
