Passing Quarter Turns

This trick is only possible on a Crossed Rig.

Two flyers swing on opposite bars of a bar-to-bar rig. They are both swinging on one side of their bar (both right or both left). As the approach the middle they both make quarter turns the same direction (both right or both left) to catch bars on the perpendicular rig.

If they both catch the new bar on one side (or move to the side at the platform) then they can repeat the trick indefinitely, moving around the rig.
