        piecewise - lots of moving circles intersecting in interesting ways.


        piecewise  [-display  host:display.screen]  [-visual  visual] [-window]
        [-root] [-delay number] [-count number] [-ncolors number]  [-colorspeed
        number] [-minradius number] [-maxradius number] [-no-db] [-fps]


        This  draws  a  bunch of moving circles which switch from visibility to
        invisibility when they intersect.


        -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
        -window Draw on a newly-created window.  This is the default.
        -root   Draw on the root window.
        -delay number
                Per-frame delay, in microseconds.   Default:  5000  (0.01  sec-
        -count number
                Number of circles.  Default: 32.
        -ncolors number
                Number  of  colors,  only  one  of  which  is  used  at a time.
                Default: 256.
        -colorspeed number
                How fast the color changes (0 - 100).  Default: 10.
        -minradius number
                Minimum circle radius  (as  a  proportion  of  screen  height).
                Default: 0.05.
        -maxradius number
                Maximum  circle  radius  (as  a  proportion  of screen height).
                Default: 0.2.
        -db | -no-db
                Whether to double buffer.
        -fps    Display the current frame rate and CPU load.


        DISPLAY to get the default host and display number.
                to get the name of a resource file that  overrides  the  global
                resources stored in the RESOURCE_MANAGER property.
