In this chapter, we learned the basics of the particle replicator. We used the advanced Animation Engine to animate a real-world object. We also used advanced texturing techniques to place a movie on an iPhone screen. Finally, we used expressions to drive keyframes based on audio. All of this to create one great iPhone ad! Not bad for just a few hours, eh?

In the next chapter, we're going to learn how to optimize our scenes for performance, and get to know what affects performance, and what to look out for. There are some simple tricks that can keep your render times reasonable and some simple mistakes that can make rendering times ludicrously long.
