NAME
       halftone - simple halftone pattern of moving mass points

SYNOPSIS
       halftone  [-display  host:display.screen]  [-visual  visual]  [-window]
       [-root] [-count number] [-spacing number] [-sizefactor number]  [-delay
       number]   [-minmass   number]   [-maxmass  number]  [-minspeed  number]
       [-maxspeed number]

DESCRIPTION
       Draws the gravity force in each point on  the  screen  seen  through  a
       halftone  dot  pattern.  The  gravity force is calculated from a set of
       moving mass points. View it from a distance for best effect.

       -minmass number
               The minimum mass of each mass point. Default: 0.001

       -maxmass number
               The maximum mass of each mass point. Default: 0.02

               The maximum speed of each mass point. Default: 0.02 -delay num-
               ber Per-frame delay, in microseconds.  Default: 10000
