This is the program that presents a storyworld to the player, offering dramatic choices as the story develops. It presents the Deikto sentences and the faces of the characters the player is interacting with. Each character has a unique face, and their facial expression reflects their emotions. There is a very wide palette of available facial expressions, which befits the richness and variety of possible emotional states.

Here is a very rough mockup of a basic plan for the screen layout (click to see bigger version):

This shows a particularly tense moment in an imaginary storyworld. A nasty character by the name of Knifer has just issued you a threat: Give your bicycle to him or he'll knife you. You see Knifer's ugly face leering his threat at you. Now it's your turn to respond. On the right side of the screen, you get to talk back to Knifer in the same language that he uses to communicate with you: Deikto. In this case, you have two stark choices: accept the threat, or reject the threat. There is a third choice, "take the initiative", which means you can try to take the conversation in a completely new direction ("Hey, what you do you think of them Yankees?"), but it probably will serve only to infuriate Knifer.
