In my unreleased oldie which I have renamed about 5 times since 1990, 
an audio studio for the CoCo 3, I take half-steps from the last mouse 
position to the current position up until a distance of 2 to 4 or so 
then I update both the same.  This makes for a smooth moving cursor 
that has a professional feel to it.  The math is terribly simple and 
done by some bit shifting.

Jeweled will have the same hand cursor and smooth joystick/mouse 
movement.  In my screenshot you can see my failed attempt at plotting 
the hand sprite for the cursor.  It appears as a vertical bar 7 
columns across and 5 rows down.  And it's flickering terribly which 
means I haven't gotten that far with it yet.
