We've seen stereo pairs before: you look "through" the screen until the two images overlap. That third image--in the center--will be in 3D. Hint: look between the L and R at the top, then make them overlap. The view directly below will be 3D. That places you right in the cockpit with Koenig and Helena. Now you're off and running with a fanfic adventure. If Space 1999 isn't your bag, there are other stereo sets you can do a search for. Harry Potter is one example.
