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.
