SYNOPSIS

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

number] [--ncolors number] [--colorspeed number] [--minradius number]
[--maxradius number] [--no-db] [--fps]

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

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.
