You have probably guessed by now how the haiku¹ program works. It selects a form (either randomly from the four available, or as directed to a specific form), uses that form to select words of the prescribed grammatical classes from the vocabulary fields, and strings the selected words together to produce a "poem." While the underlying details are remarkably simple - and completely mechanical - the verses produced can be downright insightful and melodic. This is mostly a reflection of the vocabulary chosen and its relation to the grammatical forms. Lets experiment with these components of the program.

1. Examine the four grammatical forms that are available. Edit one of them to include what you think might be an interesting form.
   
   
2. Select the form you chose to edit, and then set the program to "Use Visible Form". Produce poem verses using you new form. How do they compare to those produced by the original program?
   
   
3. Now, edit any or all of the vocabulary fields. Add words to different categories, and see what verses result.
   
   
4. Record on a sheet of paper three interesting verses that were produced by your modified program.
   
   
5. Pick one verse from each of you three lists (the poems produced by humans, those produced by the original program, and those produced by the modified program). Pass the three verses chosen to a classmate, friend, or your instructor, and see if they can determine the author of each.
