There are similarities between this type of 3D animation and the type in my scene. That is, two slightly offset images are alternately displayed. And because of that fact, I found that I could carefully drag the top image in your scene with the Move tool left and right to change the "pivot point" of the shifting images. At a certain point, the metal poles in the foreground appear to not shift at all, but the boat and other things in the background will shift. At another point, the cabin of the boat appears to be stationary while other things closer and farther appear to shift.

I plan on taking photos of things around my house and making animated 3D images of them. If I get any really interesting ones, I'll upload them in a scene.

Nice job, and I'm glad that you found this technique!

I took the photos 10 years ago. I had them side by side and would look at them cross-eyed. A 3D image appears between the two images. A good free program for setting up the initial alignment can be found here. The images are easy to take. Lean on your left foot and take a picture, then lean on your right foot and take a picture. If you look cross-eyed for too long, your eyes will get stuck in that position. I now have to wear corrective lenses to uncross my eyes.

That's what my mamma warned me about when I was six! Luckily for me, I obeyed her, and now that I'm a little older, my eyes are not stuck in the crossed position.
