Hopefully this project will be completed before the deadline for the 1kB contest. The skeleton is 3D printed PLA ball joints. The ball joint used was found on thingiverse (https://www.thingiverse.com/thing:70366). The muscle or guide wire has yet to be decided, but will likely be nylon string or fishing line. An old arduino uno will provide a driving signal to the servo. Regardless of whether or not I make the deadline, I will post the final results.
