Please send me examples of good OOP code

One problem that I have when discussing OOP is the “no true Scotsman” fallacy. Whatever criticism one has against OOP can be always rejected with “that's not a real/good OOP”.

So here is the dare – send me links to public Open Source projects that you think are an example of superb and excellent OOP code. It doesn't have to be fancy, but it has to be a real project doing something useful end to end: not a library or a framework. You can find the mail link at the bottom. I did some Google searches looking for similar questions (and answers) and I haven't really found anything useful.

Please share this post if you're also interested.

My plan is to collect some projects, pick up handful that I find best, and then apply common OOP criticism to a concrete code that other people find the best in class.

I will make sure to edit this post and add them below.

Thank you!
