Yeah, it only two pictures. I've been making some 3D pictures, and all you do is take two pictures side by side (with the lenses about where your eyes are). Then you give the left a red hue and the right a blue hue and overlap them (can be done with photoshop).
The red/blue lights in FPSC act the same as the red/blue hue on the pictures, but the lights also cast shadows. All you need to make sterioscopic pictures is hue because the shadows are already in the pictures, but sence the lights are making shadows it works the same way.
I took some more screenshots. I also found out that it works alot better if you make the rooms almost purple with the red/blue lights.
The download is the rest of the pictures in a zip file.
