grapevine-step

Travel sideways: step out, cross the trailing foot behind, step out again, and tap — a smooth grapevine. Loop, moving with root.x.

How

• Step out (lead): LeftUpLeg:[20,0,150] (slight abduction), arms easy (*UpperArm:[0,0,±75]), root.x moves.
• Cross behind: trailing foot on the toe (RightFoot:[60,0,0]), small torso turn (Spine:[0,10,0]).
• Step and tap. Loop.
