Review

The animation approach we used so far is "ad hoc"
This means that we have to write the same code in every application that uses animation

Using Sprites

A Sprite:
- Visual content that is responsible for its own dynamic behavior
A Stage:
- Forwards timer, mouse, and keyboard events to Sprite objects
