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

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.
