Kevin Hoang Le and his team have created an Ajax Chinese Chess game.

It’s true Ajax (as opposed to just Javascript) since all the move computations of the “computer” player is done on the server and the data is passed in JSON format back and forth.

The Javascript code is entirely unobtrusive and weights only about 30 kB (uncompressed). This code uses the excellent Mootools and JavaScript VectorGraphics libraries. On the server side, it’s built in Python using the Django framework.

Ajax Chinese Chess features the following: animation, drag and drop, fast loading (thanks to lightweight Javascript code mentioned above and small footprint Mootools), no plugin required and cross browsers/cross platforms.
