Java 4K Programming Contest

First of all : Happy new year !
Java4k is a very funny contest . The best part is that you don't have to write 3 months to create a decent entry. You could create a nice game (that has to be under 4 kilobytes in size !!!) in a single night .All you have to do is to respect the rules and create a fun game.Even if you won't write a game you can just look at the other games an have tons of fun playing those small unique games.
Here is the announcement :
The Java 4K Programming Contest is the ultimate byte-squeezing Java challenge! Using only 4096 bytes, competitors use every trick up their sleeve to create an entire game.

Submit your games here before March 1st, 2007!

Contest Prizes
* 6 months free playtime of Wurm Online, courtesy of Mojang Specifications!
* Top 5 entries score a free copy of Tribal Trouble, courtesy of Oddlabs!

Basic rules are as follows:
* The final game package (byte code + resources) must be below or equal to 4096 bytes

* Must be a playable game (cannot be a pointless animation)

* Must be pure Java (no JNI)

* Must be self-contained- no external resources (e.g. loading an image from a website)

* No Pack200

* No external libraries may be used - you must use the libraries that come with the “public” version of the JRE

* No soundbanks may be used because they are not a default part of the “public” JRE. You will have to create your sounds at runtime rather than use MIDIs.

* The presentation (jar, class, or other) does not matter, as long as the code can be executed without a command line

* The target JRE is 1.5 (Java 5) or lower

Specific questions and comments can be made at the official Java 4K forum.
