Draw on the specified window.

--mono

If on a color display, pretend we're on a monochrome display.

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.

In seuss mode, alternating striped curves will be drawn.

In ramp mode, a color ramp will be drawn.

How much of a delay should be introduced between steps of the animation. Default 100000, or about 0.1 second.

--colors integer

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.
