I've done this in ESA's modified Airbus A300 in Bordeaux, France. We got approx 25s of weightlessness and around 1.8g just before and after. Google for "student parabolic flight campaign".
Some ten years ago I built my own shutter glasses. One large LCD in front of each eye. They can either be transparent or go black. Synchronized with the display I let every other screen update go to one eye, and the rest to the other eye. This gives a virtual refresh rate of half the normal refresh rate, but I could manipulate what each eye should see. Based on this I can tell you that most normal people (all that tried my system) use triangulation and not focus to perceive depth. I also found out that kids find it easier to focus "wrongly" than adults.
1. Cellophane is not polarizing. It rotates the already existing polarization 90 degrees.
2. If you are looking at an object in front of you, you are _always_ crossing your eyes. The closer the point you are looking at, the more you cross your eyes.
3. The images don't need to be displayed in the same space. Where they are to be displayed depends on where you want your 3D image "float around". With the solution in the article, you can never present an object that appears to float _behind_ the screen, but that is not always what you want to do and depends on the application.
What the article DOES present is a way to use cheap cellofane as a large halv-waveplate and an example application of this.

The google map is nice, but I like the technology behind this map a lot better. Panning and zooming responding instantly!

Oh. I forgot to add.
We did it 30 times in a row. That's what gives it the name.

They already landed successfully.
Well spoken!
