This is just a quick pic of this model rocket my cousin built. You just gotta cross your eyes. This is simpler if you own sunglasses, reading glasses or prescription glasses. I didn't do this one in red/cyan because there was red and blue in this picture.
Took a minute to get the images lined up, but once I did, that was awesome. Now my vision is blurry...
If you cross your eyes regularly for some reason, like I do, you won't have a headache and your vision won't be blurry.
I could never get those things. I had a poster of the F117 Stealth Fighter that was hidden in some weird kaleidoscope looking poster. They said if you stair at it long enough the image will pop out. I only got to work once and haven't seen the jet fighter since then.
You just took a shot, repositioned, and then took another shot? Or do you have a dedicated 3D camera or rig?
