The halo program draws cool patterns based on circles.

OPTIONS

halo accepts the following options:

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 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.

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.
