From time to time, I create a game I think is worth showing. This one doubles as my AP Java final project:

Drive around tanks and planes and try to destroy the enemy army.
Eventually, I plan on releasing the source code, but it isn't quite done yet (I may even add multi-player if I can work up the will power).
Although generally I'm a C++ person, I played around with Java for this one (it being a final project for the class and all), and I must say, Java has some beautiful stuff as far as geometry, 2d graphics, etc. goes.
Anyways, enough ranting, any comments and criticism on the game are welcome.
EDIT: We won't talk about the "rocketship."
