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 :
- C, F and D are not going to move
- A, B, and E are going to swap position in the middle triangle, and A&E also have to turn 180° while moving.
When this is done, A & E have swapped sides, and the normal pattern resumes for 3 more passes.

In this pattern, B never swaps side.
