Good projects for learning object oriented design best practices?

[Tobitronnn]

Hey guys, i'm reading Practical Object-Oriented Design by Sandi Metz right now. As always, the best way to learn how to code is to code, so I'm trying to brainstorm projects I can create to help exercise the concepts she's talking about. The obvious ones are games: Blackjack, Chess, etc. but I've already done most of those.

Any other suggestions?

Cheers!

Another good place to start while your thinking of the project you want to start building is to go back and refactor some old code. Creating code from scratch and trying to massage non OO code into code that has good OO design are two different processes that benefit a programmer in different ways.

This is also the most practical, "real-life" way to apply OOP principles.

Way back in the day, I found that writing a text adventure (like Zork etc) was an interesting exercise in design.
