.SH 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.
.PP
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).
.PP
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: 
\fIfloatbg -value .87 -satmid .375 -satvar .125 -fase .25\fP,
and are such that all pastel tints are visited.
.PP
Extremely simplistic Gnome and Xfce support can be enabled with the
\fI-gnome\fP
and
\fI-xfce\fP
flags.
.SH BUGS
Floatbg doesn't use any window, button or menu,
and it can only be stopped by killing it.
