This chapter covered a lot of information regarding the movie clip object. It started with how to create it manually (which was more review than new material) and also how to create it with ActionScript. Then it went on to show some of the many different ways movie clips can be manipulated. After that, you learned how to remove movie clips from the stage during runtime using the removeMovieClip() method. And finally, we went over some of the ways to use the Drawing API.
The next chapter covers events, which we have been using for a while but have not really explained.
