wmbubble 1.50-1 (powerpc binary) in ubuntu trusty

 A Window Maker dockapp (though it does not specifically require the Window
 Maker window manager) that indicates the system load.
 .
 The more profuse the bubbles, the higher the CPU usage. The higher the water,
 the more memory being used.
 .
 Up to two user-specified programs may be launched from this dockapp.
