Last week-end I participated to the Ludum Dare game jam competition. I used the processing library (from Eclipse) to create my game. Though it would be nice to share it with you!
I didn't used any other libraries. For the sound I used JavaSound API directly. The game is fully procedurally generated and use no external images (everything is generated out of rect, ellipse and quad).
