These are modifications on my old Warp3x theme for Icewm.
Gtk2 has dark blue active menu color and Gnome has white one.
Themes have just different color schemes, everything else is like
in the original Warp3x.
To install you need to unpack the archive inside the icewm themes
directory. Local user theme dir is ~/.icewm/themes.
