It would be really cool if this worked like a Judy Clock tm.

Meaning, when you move one hand, the other will follow in the correct way (at 1/60th the speed, for the hour hand.)

I understand this MAY be more confusing, and more trouble than it's worth, but maybe Telling time 1.5 could have the crutch of only showing legitimate times and haveing the user move only minute hand (winding it around multiple times), while telling time 2 could make the user move hands manually.
