One of the most powerful techniques in lm is magnifying the face of an actor to give the audience a feeling of intimacy with that person. Although you won t see that technique in most presentations, new technologies continue to transform the presentation landscape. For example, in some presentations, an IMAG image magni cation camera will zoom in on a presenter s face while he or she is speaking at a live event. The image is often featured in a split-screen format next to the speaker s PowerPoint slides on a wide screen. If you have the chance to have your face magni ed on a screen, embrace the opportunity you re giving the audience a chance to see you up close. But before you do, rehearse using a live camera similar to the one in the presentation along with the event producers, who will arrange for lighting and makeup to make sure that you look good on the big screen.

Some of these language tasks are generic enough that they could be useful in other applications, so you ll develop a basic library for them. This will make your bot code simpler, and give you a library to use in other applications if you need. Logic and methods that are specific to bots can go in the bot s source code, and generic methods that perform operations on text can go into the library. This section covers the development of a simple library, including testing and documentation.

Polymorphism is at work every time you can do something to an object without having to know exactly what kind of object it is. This doesn t only apply to methods we ve already used polymorphism a lot in the form of built-in operators and functions. Consider the following: >>> 1+2 3 >>> 'Fish'+'license' 'Fishlicense' Here the plus operator works fine for both numbers (integers in this case) and strings (as well as other types of sequences). To illustrate the point, let s say you wanted to make a function called add that added two things together. You could simply define it like this (equivalent to, but less efficient than, the add function from the operator module): def add(x, y): return x+y This would also work with many kinds of arguments: >>> add(1, 2) 3 >>> add('Fish', 'license') 'Fishlicense' This might seem silly, but the point is that the arguments can be anything that supports addition.1 If you want to write a function that prints a message about the length of an object, all that s required is that it have a length (that the len function work on it): def length_message(x): print "The length of", repr(x), "is", len(x)

You re going to call your text manipulation and processing library WordPlay, so create a file called wordplay.rb with a basic class:

Mark s presentation in Angleton is only a sample of how you can use BBP to unblock the engaging, compelling stories locked inside of you. When Mark entered the Angleton courtroom that hot July day to present his opening statement, he had the same PowerPoint software that you have. He just used it in an innovative way that produced dramatic results and made headline news. Every one of us has the power in our hands to teach an old dog new tricks. Even if you can t fully adopt BBP today, you can at least begin to sow the small seeds of change that will one day lead to a presentation revolution of clarity, effectiveness, and positive cultural change.

Now that you ve got the library s main file set up, you ll move on to implementing some of the text manipulation and processing features you know your bot will require, but which are reasonably application agnostic. (I covered the construction of classes in depth in 6.)
