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.

       -cycle

       -no-cycle
	       Whether to do colormap cycling.	Default is to cycle.

       -cycle-delay
	       Number of microseconds between shifts of the colormap; default 100000, or 1/10th second.

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.
