In this technique the cursor has been developed as a mutable window through which a story environment is depicted. The cursor begins as a circle of brightness, as it is moved on to the object it mutates to their appearance, eg making them glow, or become faded and translucent. It acts as a mediator between the player and the environment, illustrating the point of view of a story character. The cursor also embodies the character's interests and can be biased towards or away from specific objects in the environment. This mechanism can be used to subtly direct a player through a story plot. This technique is demonstrated in a real-time 3D environment. The scene in which it was developed begins with a woman looking around a shop for that special something.
