DESCRIPTION

       Floatbg  is an X11 program that modifies the color of the root window in such a manner that you won't see
       the color change, but after a while you'll notice that it did change, however.

       Floatbg starts with a random color and changes it deterministically by moving  through  an  hsv-model  of
       colors.   In  the hsv-model, colors are described by three parameters: Hue stands for the tint of a color
       (0 degrees is red, 60 = yellow, 120  =  green,  180  =  aquamarine,  etc),  saturations  stands  for  the
       brightness  of  the  color  (0 = white, 1 = bright), and value stands for the intensity of the color (0 =
       black, 1 = normal).

       Every 10 seconds the hue (tint) is increased by one degree and the saturation (brightness) is changed  by
       a  sinus  over  the  hue.   (The frequency of this change can be adjusted with the -time parameter.)  The
       shape of this sinus can be adapted with the options -satmid, -satvar and -fase.  The value (blackness) is
       fixed and can be set with the option -value.  The default values are: floatbg  -value  .87  -satmid  .375
       -satvar .125 -fase .25, and are such that all pastel tints are visited.

       Extremely simplistic Gnome and Xfce support can be enabled with the -gnome and -xfce flags.

BUGS

       Floatbg doesn't use any window, button or menu, and it can only be stopped by killing it.
