Spinning Action for characters
Having a "spinning" action for characters as an enter/exit animation would allow users to do some fun things.
1) mild mannered citizen spins and turns into a super hero
2) Casually dressed person spins and then appears "dressed to impress" for work or a date
3) Young boy spins and turns into a teen who spins and turns into a young adult who spins .... etc etc.
Just some food for thought.
