NAME
       piecewise - lots of moving circles intersecting in interesting ways.

SYNOPSIS
       piecewise  [-display  host:display.screen]  [-visual  visual] [-window]

       number] [-minradius number] [-maxradius number] [-no-db]

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

OPTIONS
       -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.

       -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-
               onds.).

       -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.

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.
