User controlled Animations

In the last few chapters, we've been exploring timelines as a way to edit and control a large pile of tweens. That's not changing in this chapter as well, but we're taking our tweens to the next level by creating dynamic animations. The animations will be controlled and changed directly by the user. The idea behind this chapter is to open up your eyes to the possibilities of user interactions and their affect on animations. Animations don't have to be something preconfigured completely in advance - they could be triggered by: users actions, music, time, data and other numeric factors.
