-; The object of the game is to find four hidden balls by shooting rays
-; into the black box.  There are four possibilities: 1) the ray will
-; pass thru the box undisturbed, 2) it will hit a ball and be absorbed,
-; 3) it will be deflected and exit the box, or 4) be deflected immediately,
-; not even being allowed entry into the box.
-; 
-; The strange part is the method of deflection.  It seems that rays will
-; not pass next to a ball, and change direction at right angles to avoid it.

-; Rays which enter and exit are numbered.  You can see that rays 1 & 5 pass
-; thru the box undisturbed. Ray 2 is deflected by the northwesternmost
-; ball.  Likewise rays 3 and 4. Rays which hit balls and are absorbed are
-; marked with H.  The bottom of the left and the right of the bottom hit
-; the southeastern ball directly.  Rays may also hit balls after being
-; reflected. Consider the H on the bottom next to the 4.  It bounces off
-; the NW-ern most ball and hits the central ball.  A ray shot from above
-; the right side 5 would hit the SE-ern most ball.  The R beneath the 5
-; is because the ball is returned instantly.  It is not allowed into
-; the box if it would reflect immediately.  The R on the top is a more
-; leisurely return.  Both central balls would tend to deflect it east
-; or west, but it cannot go either way, so it just retreats.

-; At the end of the game, if you've placed guesses for as many balls as
-; there are in the box, the true board position will be revealed.  Each
-; `x' is an incorrect guess of yours; `o' is the true location of a ball.
