Circulate from a two faced line:
The paths for this move can be visualized as a 2 lane, one way
road running around the square. Dancers can be moving in one
or both lanes, but all will move the same direction - either clockwise (shown here)
or counter-clockwise - and no dancer is allowed to change lanes.
Note this well:
There is an inside "lane" and an outside "lane"
STAY IN YOUR OWN LANE and walk forward.
