SYNOPSIS¶

beats [--display host:display.screen] [--visual visual] [--window] [--root] [--window-id number] [--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.
