I dug out some old stuff I did while trying to learn Java. It's a bunch of simple games written as Java applets. As this code is laying dead since 2000, it decided to release it as open source project. I hacked up a website, so check it out:
There are four games: tic-tac-toe on 10x10 board, two puzzle games similar to Master Mind and Memory and good old Tetris. All those are playable online, so if you're looking for something fun to kill a few minutes, this might be for you.
