bluetile 0.6-3 (ppc64el binary) in ubuntu utopic

 Bluetile is a tiling window manager designed to integrate with the
 GNOME desktop environment. It provides both a traditional, stacking
 layout mode as well as tiling layouts where windows are arranged to
 use the entire screen without overlapping. Bluetile tries to make the
 tiling paradigm easily accessible to users coming from traditional
 window managers by drawing on known conventions and providing both
 mouse and keyboard access for all features.
