Jugglers needed (base version): 6 intermediate
This is a variation of pistons for 6 jugglers.
Aidan also came up with a variation where 2 jugglers swap sides in the pattern every 3 passes.
Imagine the jugglers have done the first 2 passes (see the first 2 diagrams
above). Now replace the third diagram above by the first one on the left.
The passes are the same, but the movement that follows is going to be
In this pattern, B never swaps side.
