Hey, that's neat!

Mmm... the rotation doesn't quite seem right though... I can see at least
one ball rotating in the opposite direction to the way it's rolling...
(Well, I suppose it might be possible on ice ;-)

I haven't been on this board much for the past few months, but this is
definitely an interesting simulation; it appears to address problems that
I'm currently puzzling over... Nice to know they're solvable.

Thanks.
Andrew.
