I wrote a tetris clone using Processing.org. I used no game framework and simply graphic and tweening libraries. I did it in about 6 weeks during a vacation between contracts. It’s the hardest thing I’ve ever done. I wrote a lengthy post about how I constructed it.
I will have the source published as soon as I decide on a git hosting service.
