The JGD-Black GTK+ 2 theme complements the JGD-Black Openbox theme, which is included with this package.
GTK2 stands for GIMP ToolKit, version 2, a toolkit for building graphical user interfaces. GTK offers two versions, of which both can be themed.
JGD-Spring Awakening is a fresh and friendly Openbox theme from Jason G. Designs. Features include custom icons and a bright green-to-yellow gradient title bar.
One source of confusion I ran into when creating my first Openbox theme was what pixel size to make my window decorations.
