You want a hard problem that's not below you? How about writing a program can that generate sensical poetry without using a sample of chopped poems, but only a large vocabulary. Even more so, have it generate original poetry based on input of a short number of subject keywords.

Also, give it a plugin structure so that someone can write a haiku plugin, sonnet plugin, etc. What you need to do incorporate all of the grammatical rules of the English language.
