It's a good tool for making emoticons! 

To make a face base, type keys [ 1 ], [ = ], or [ + ].

Letters A-J are eyes, and capitalization will choose a side for them; same for the eyebrows which can be typed with letters K-O, the mole which is typed with V, and with the tears that are typed with symbols [ ` ] and [ ~ ].    P-U are mouths and will change variants if capitalized, same for the noses that can be typed with W-Z.    Numbers (besides 1) will be facial effects/features. Accessories can be created with [ @ ], [ # ], [ $ ], [ % ], [ ^ ], [ & ], [ * ], [ ( ], [ ) ], [ - ], [ _ ], [ { ], [ [ ], [ | ], [ \ ], [ : ], [ ; ], [ " ], and [ ' ].    Hair can be typed with [ ] ] and [ } ], and tone indicators (for you silly typers like me) can be made with [ , ], [ < ], [ . ], [ > ], [ / ], and [ ? ]
