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] [-fps]

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.
