.SH DESCRIPTION
The \fIbeats\fP 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.
