After reading this thread...
I started working on a new template. The idea was to show a way to animate buttons. It grew into a "United States Capitals Quiz".
The four buttons don't just turn light-blue on mouse over, it transitions from dark-blue to light blue. This is more advanced than regular button states, as this includes animation.
If you want to learn how to make a quiz, or if you want to find another way to manage button states, you might find this template helpful.
