Give me your Java and Python code

Hey,

at the moment I'm heavily procrastinating, so I thought it's a good
time to refresh my language knowledge

Therefore, I'm asking if one of guys has a small game (around 10k loc maybe)
written in Java or Python that I can tinker around with.
Ideally, the game has only a few library dependencies. Also, the code should
be "java-ish" or "python-ish" (as opposed to translated from, say, C), so I get
to learn common idioms and standard libraries.
Open source games are fine, too.

So, any suggestions?
