Here are a couple more animated gifs that demonstrate my experimentation with focal point within the frame. As you can see from the two images below, changing the focal point can have quite a significant impact. The top images fp is set to the plant in the background, and the bottom image has its fp set on the small group of flowers protruding in the foreground. The stereo gif's focal point can ultimately determine the 3D effect given (i.e. whether the wobble occurs within the background or foreground).
