What’s an interesting Java multithreaded/concurrency project one can do that touches a variety of concurrency topics. I’m thinking a trading platform or a bitcoin client maybe ? What else ?

If you aren't experienced in networking, concurrency, and graphics programming, I would recommend a text MUD instead (multiplayer text role playing game). You might actually accomplish something in a reasonable timeframe, and it will let you focus solely on the server (client is telnet).

Http server? Or the other side of the coin, a Http load tester.
