       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

       -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.
