From parallel waves: Those facing out in each wave do as in Twin Orbit Circulate (above). Those facing in will accomplish a "Circulate two positions" but will use a right hand star to do so (from right hand waves -- use a left hand star from left hand waves). Centers from one wave finish as centers in the other wave; ends finish as ends; all dancers finish facing in. The movement finishes with facing lines of four.
