I think the main point is the educate and to learn new or useful things as I mentioned before but this project not just about the content, I mean, the roman or arabic numbers and the conversion between them — it is a good iPad/iPhone sample project as well because it contains the main and default techniques on iPhone/iPad.
this is good place to view the main techniques for the beginner developers, they could see how the rotation technology works, how to manage the views and how to take cafe of any table and the table's datas and how to connect the table's datas with the CoreData data storing system.
unfortunately, the source code is not available in spite of the Pergament is a free application, no one can download and examine the code and the class structure but I'm here to answer any question which you would be interested in.
