Much Islamic art applies principles of geometry and repeats simple patterns to form complex forms. For example, the Egyptian Motif above has six overlapping rectangles.

In this project, you will learn how to extend your pinwheel code from Unit 1 to create such intricate patterns.

In this project, you will begin to build the game Mastermind™. In this game, one player selects a sequence of four secret colors, and the other player tries to guess it.

Siri and other robots are programmed to generate language. Siri speaks; some robots write. You have developed a program, gossip, that writes. Now, you can extend the computer's abilities with language by developing a reporter block, plural, that takes a noun as input and correctly spells and outputs the plural.

Spelling a plural can seem almost automatic for a person, but it is not simple: a computer needs an algorithm to do that task.

You can improve plural to work correctly with more words.

You will improve your Railroad Crossing project so that it uses the list of data collected at the crossing to determine if a train should be sent on a different track by operating a switch for a turnout.
