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. __-cycle__ __-no-cycle__ Whether to do colormap cycling. Default is to cycle. __-cycle-delay__ Number of microseconds between shifts of the colormap; default 100000, or 1/10th second. !!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. !!SEE ALSO X(1), xscreensaver(1) !!COPYRIGHT Copyright 1993 by Jamie Zawinski.
