These sculptures use the same system as the Parker solar probe (which began flying towards the sun in 2018). The left solar panel is the left eye, the right panel right eye , and the two shades two hands, shielding the eyes. If the left eye sees the sun from behind the hand, it turns the motor right, if the right eye sees the sun from behind the hand, it turns motor left, and through this is orientated towards the sun.
