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.
