Speaking as a novice to this area, I do understand that what we learn with may not be (and usually isn't) production-ready code, I do see Nick's suggestion as being one that is easy to understand, 
easy to measure, and good for piquing interest.

At least, I'm now interested.  :)  (look ma!  bowling for circles!)
