OPTIONS
halo accepts the following options:

| -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. |
