NAME
       halo - draw circular patterns


SYNOPSIS
       halo  [-display  host:display.screen]  [-foreground  color] [-background color] [-window] [-root] [-mono]
       [-install] [-visual visual] [-count int] [-delay usecs]  [-mode  seuss  |  ramp  |  random  ]  [-animate]
       [-colors integer] [-fps]


DESCRIPTION
       The halo program draws cool patterns based on circles.


OPTIONS
       halo accepts the following options:

       -window Draw on a newly-created window.  This is the default.

       -root   Draw on the root window.

       -mono   If on a color display, pretend we're on a monochrome display.

       -install
               Install a private colormap for the window.

       -visual visual
               Specify  which  visual  to  use.   Legal  values are the name of a visual class, or the id number
               (decimal or hex) of a specific visual.

       -count integer
               How many circles to draw.  Default 0, meaning random.

       -mode seuss | ramp | random
               In seuss mode, alternating striped curves will be drawn.

               In ramp mode, a color ramp will be drawn.

               random means pick the mode randomly.

       -delay microseconds
               How much of a delay should be introduced between steps of  the  animation.   Default  100000,  or
               about 0.1 second.

       -colors integer
               How many colors to use.  Default 100.

       -animate
               If  specified,  then  the centerpoints of the circles will bounce around.  Otherwise, the circles
               will be drawn once, erased, and a new set of circles will be drawn.

       -fps    Display the current frame rate and CPU load.


ENVIRONMENT
       DISPLAY to get the default host and display number.

       XENVIRONMENT
               to get the  name  of  a  resource  file  that  overrides  the  global  resources  stored  in  the
               RESOURCE_MANAGER property.
