This is the camera I've always imagined Blinky, the three-eyed fish from The Simpsons, would use:
Behold the 120 Tri-lens from Chinese camera manufacturer 3D World. I won't even pretend that I understand how it works (like why it needs the 3rd lens to capture a stereo photo - aren't two lenses enough? I have 2 eyes and I see in 3D ... )

Clearly, you have never seen a medium format stereo pair. They are stunning. Mind blowingly awesome. The images this camera creates are like actually being there. No other 3D image display technology can beat medium format stereo slides.
If you think 3D is anaglyphs or cross-eyed viewing of an image on an LCD monitor, then I'm sorry for your ignorance.
If you are willing to invest some time, you can get similar images using this, less expensive camera:
If you are willing to learn to do some chemistry, you can develop the slides yourself (it is not as hard as people might tell you) for about $2 a roll.
If you have red/blue anaglyph 3d glasses like from the Spy Kids 3 or Sharkboy movies you can see 3d pictures for free that I've taken at my site:
I use a custom digital rig and can also do traditional stereo pairs, which are superior to anaglyph (since they don't filter colors) but anaglyph glasses are more accessible to the masses with simple cardboard glasses. Hey, I rhymed ;)
