We have seen the power that lists and variables give us to create dynamic, flexible, and fun projects. As you worked through this chapter, you probably realized that we could have used lists in some of our previous projects. For example, our scripts in Chapter 5 would have been much smaller had we used lists.

We learned how to manipulate lists, a special kind of variable, to collect a group of related items. We continued to explore variables by using them to store text. The mod block helped us identify intervals as we iterated through our list. We used a variable to keep track of the interval so that we could program specific events based on when an interval occurred.

When we're working with text, it's natural to want to capture keyboard input from our user and then use that text in our scripts. Thanks to the new features in Scratch 1.4, we saw how easy it was to incorporate test strings from the user.

Our programming knowledge has been accumulating nicely to this point even though you may not know it. We're ready to apply everything we've learned, plus more, in our next project. Get your money.
