NAME

beats - create offset beating figures

SYNOPSIS

beats [-display host:display.screen] [-visual visual] [-window] [-root] [-delay number] [-count number] [-cycle number] [-wireframe] [-fps]

DESCRIPTION

The beats program draws balls that move around at a slightly different rate from each other, creating interesting chaotic and ordered beating patterns. Each cycle / pattern is created such that it finishes as a single line of balls at the top of the screen, so that the patterns can smoothly transition between each other.

-delay number: Per-frame delay, in microseconds. Default: 30000 (0.03 seconds.).
