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.
