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
different : In this pattern, B never swaps side.
