My technique is to store the positions of all the balls at the start,
and stop recording when they're back there. It's a miserable system, but
it kindasorta works for most patterns.
Ideally you'd calculated the lowest common multiple of the style length
and the pattern length, and stop recording when you hit that exacty
point. Alternatively, every time the pattern repeats, check to see if
the style is at a repeat...

Aye. IIRC povray is an easy enough format, you're probably better off
adding it as a "print" target to jmdlx, although if commandline is your
aim, perhaps aajm is a better bet.
