As the name suggests, this little program lets you change your gtk+ 2.0
theme. The aim is to make theme preview and selection as slick as
possible. Themes installed on the system are presented for selection
and previewed on the fly. For a comprehensive demonstration there's a
large variety of widgets.
It was originally derived from Gtk Theme Switch, but what started out
as a hack to remove various nuisances now shares no code whatsoever
anymore with the original.
