This demo video shows how a flexible hub drives the graphic display on the host computer. The flexible hub has rotational potentiometers at the hinges, which give a resistance value based on the angle bending between the socket arms. The host computer translates these resistance values to their corresponging angle. The Lisp graphics display uses these data to display the model.
