99  * so that it `sticks out' upward and leftward.  Except for shape 6,
101  * shape 6's center `wobbles' as it rotates, so that while it `sticks out'
109  * The shape is moved steadily downward until it collides with something:
110  * either  another shape, or the bottom of the board.  When the shape can

121  * rotating the current shape.  Due to symmetry, each shape has exactly
