The artificial hand, attached to the right arm as an addition rather than as a prosthetic replacement, is capable of independent motion, being activated by the EMG signals of the abdominal and leg muscles. It has a pinch-release, grasp-release, 290 degree wrist rotation ( clockwise and anti-clockwise ) and a tactile feedback system for a rudimentary "sense of touch".

Whilst the body activates its extra manipulator, the real left arm is remote-controlled / jerked into action by two muscle stimulators. Electrodes positioned on the flexor muscles and biceps curl the fingers inwards, bend the wrist and thrust the arm upwards.

The triggerings of the arm motions pace the performance and the stimulator signals are used as sound sources, as is the motor sound of the Third Hand mechanism itself.
