I downloaded his Wii app that shows the little red/white discs, and bought a battery powered Wii-bar thing that had the IR leds in it and strapped it to my head. Can confirm, the 3D effect is 100% spot on, even the smallest move of your head caused the display to adjust perspective and your brain is totally fooled into thinking the Wii display is a just a window into a 3D scene. tbh, it was the only cool thing I actually did with my Wii!

Surely the depth effect only worked with one eye closed?

  Nope, works with both eyes. Your brain takes a lot more cues for depth than stereoscopic vision. The way the perspective changes as you move your head around is sufficient even for a flat display. It’s uncanny. Only works for one person though. If you stand at an off angle to the sensors, there’s no effect at all.

    Its amazing how the brain works... I am very cross-eyed at the moment (surgery resulted in both my eyeballs moving) and require a little plastic "stickon" that goes on the left lens of my glasses; which has prisms to redirect the light so that both eyes are looking in the same direction (prisms are fairly normal; it's the _amount_ of correction I need that is abnormal). The correction on the left lens is so bad that looking through it is completely blurry (with lots of rainbows if I'm looking towards a light). However, when looking through my glasses with both eyes, everything appears normal. I can see in stereo (which I cannot do w/o the correction) and everything is in focus. There is still _some_ rainbow effect. So, my brain is taking the "clear image" from my right eye and overlaying it with the distance information that the left eye adds to that... but ignoring the blurry image from the left eye completely. Honestly, I find it mind boggling.

And that video is over 13 years old! Too bad this idea didn't catch on more widely.

  It doesn’t seem to exist anymore, but I had a variant (literally same graphics) on my iPhone a decade ago. No fancy headgear and the effect was just as good—but instead of moving your head, you held still and tilted your iPhone. Apple later added the effect to the homescreen in iOS 7, but much more subtle.

  TrackIR is a consumer product using the exact same tech for headtracking in video games. I think it might actually be older than the Wii

Thanks. I just created a nice storage box for my Wii, got everything organized and put it on the bottom of a large pile of things to sell. This sounds way too interesting, so I'll be doing some digging, apparently. Any idea if this would work effectively on a large projector screen?

    Ha! I'm planning to do the same on the 110" I've got in the basement.
