Dummy objects in Alice can be used for blocking a scene-marking the positions for object placement and movement, similar to the way dummy objects were used in this chapter for camera positioning. The move to, turn to face, and point at instructions can be used to make objects move in relation to the dummy objects. Create a simple Alice world with two characters who engage in a dialog. Have the characters enter the scene, greet each other, and then have one character tell the other character a joke. Use dummy objects for blocking the scene and for camera placement
