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]


The halo program draws cool patterns based on circles.


halo accepts the following options:

Draw on a newly-created window. This is the default.
Draw on the root window.
If on a color display, pretend we're on a monochrome display.
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.
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.
Display the current frame rate and CPU load.
