13. An input surface system, comprising:
-
a chassis; an array of first balls rotatably supported by the chassis; an array of second balls positioned proximate the array of first balls, the array of second balls having a second ball-to-ball pitch that is smaller than a first ball-to-ball pitch of the array of first balls, wherein rotation of either of a first set of the array of first balls and a second set of the array of second balls causes rotation of the other of the first set of the array of first balls and the second set of the array of second balls.
