Big Overhead Wave

A large attention-getting wave: the arm goes straight overhead and the whole arm sweeps side to side.

How (right arm shown; mirror to Left by negating the Z values)

• Arm overhead with a near-straight elbow: RightForearm:[0,0,0].
• Sweep the raised arm by rocking RightUpperArm Z around overhead (90): 70 <-> 110 (left arm: -70 <-> -110).
• Add a small opposite torso lean (Chest Z) for energy.

Example

• "give a big wave over your head" -> {"durationMs":2000,"say":"Hey, over here!","sequence":{"loop":true,"frames":[{"t":0,"pose":{"RightUpperArm":[0,0,70],"RightForearm":[0,0,0],"Chest":[0,0,-8]}},{"t":0.5,"pose":{"RightUpperArm":[0,0,110],"RightForearm":[0,0,0],"Chest":[0,0,8]}},{"t":1,"pose":{"RightUpperArm":[0,0,70],"RightForearm":[0,0,0],"Chest":[0,0,-8]}}]}}
