robotfindskitten is a "Zen simulation", originally written by Leonard Richardson for DOS. It is a free video game with an ASCII interface in which the user (playing the eponymous robot and represented by a number sign "#") must find kitten (represented by a random character) on a field of other random characters. Walking up to items allows robot to identify them as either kitten, or any of a variety of whimsical, strange or simply random Non-kitten Items (NKIs).
