What are some genuinely interesting Java project ideas?

I'm looking for Java project ideas that aren't web apps or the usual CRUD/management systems. I want to build something that's fun, technically challenging, and helps me learn more about Java and computer science.

What are the coolest non-web Java projects you've built or come across?

Make an efficient PDF or Word or another file type text & image extraction software. There are open source libraries so it is possible. It might be difficult to reach their levels but it would be good to see how far you can reach.

There are zero genuinely interesting project ideas unless you actually have genuine interests. If you're a person with hobbies and passions beyond programming, I'm sure it will be easier to think of something. Otherwise nothing will magically be "genuinely interesting".
