Zen Bridge started out as a simple 2 player game of Hex (also known as Nash and a few other names), but quickly evolved into a chance to learn about asynchronous networked gameplay and, due to a requirement by carriers, some basic AI.

Players of Zen Bridge simply entered the username of the person they wished to challenge and that person would receive an invitation, once accepted the games synchronize and the players are able to play as many games as they wish against each other. Due to the design players can even continuing playing after losing cell phone service.

The game was done for a few months but shelved because it had horrible programmer art. My brother redid the art and it was released a short time later.
