The Roll 'n Rocker accessory

The Roll 'n Rocker is an accessory for the Nintendo Entertainment System made by the company LJN. It consists of a large piece off plastic that the player rocks back and forth instead of using the D-pad. However, the player still needs the controller to press the A and B buttons. It is notorious for working very poorly, and sometimes not at all. It is compatible with all NES games excluding Lightgun games.
