'Mind Reader' is an applet variation of a childrens novelty game. 
The player is requested to think of a number between 1 and 63.  The player
is then shown a set of six cards with different variations of numbers
between 1 and 63.  The player is asked to indicate yes or no if their
chosen number is on the card.  After the last card, the players's
chosen number is revealed, as if by mind reading magic!
