Bruzd-Nodoka is a dark gtk+ theme for the Nodoka engine, based loosely on a gtkrc I threw together for screenshots on the Nodoka engine page but subsequently lost.
While I was at it, I decided to bring in a metacity theme that I liked with it. The result is the following download, which contains the Bruzd-Nodoka gtk+ theme and BlendedSmallDoubleRound by ECHM in a single metatheme.
It defaults to the GNOME icon theme because I don't know of any icon themes that go well with dark themes and it really isn't that hard to change from the tolerable default GNOME provides.
Install it by dragging and dropping into the appearance dialog.
This gtk+ theme requires the Nodoka engine, which may be found at:
