Update 2:
Thanks youtube for letting us post comments without stupid g+ again. I guess I will have to start responding to comments again :)

Oh and to you that still don't get that the waving around of the glasses is to let you see the different views that each eye is subjected to; Think before commenting. This is to show the effect and that it can be done. Not to show you the entire movie...
And no, you can not and will never get 3D on your monitor at home from this clip in any way.

Update: Due to the shitty way Google now treats commenters and forcing people to use Google+ in order to comment and even reply, I am thinking of leaving youtube. I will then delete all my videos ofcource. Since I refuse to use Google+ I can't even write this in the comments section. Thanks Google, hope the person at Google responsible for this finds out his nuts don't work or have to be cut off!

Here's a small clip showing a movie actually playing on my home cinema.
I use two projectors each equipped with the filter from one of the eyes of a pair of RealD 3D glasses. (Bought at the cinema.) You mount the filters as if the projector is wearing the glasses. You also need a program that can read a blue-ray or dvd with a stereo movie on it. You can't just use a regular movie. 3D can't be created from a single 2D movie so don't bother asking...

I am getting a lot of video-replys from people trying to duplicate this in different ways. I need to clarify a few points...

1. I use two projectors

2. The projectors are showing a DIFFERENT version of the film designed for tha eye their filter matches.

3. The source of the video is a blu-ray with a frame-progressive 3D version of the movie. This means that it contains both versions interleaved so that it would play on a single projector or TV and you'd need shutter-glasses to view it.

4. This was ment as a demonstration of home-use. It shows that indeed the image seen in left and right filter is different.

5. The 3D move was split into two streams. One for each eye.

6. The application used to play back the two streams is called Stereoscopic Player and the demo allows you to try it out for 5 minutes each time you start it.

7. You NEED a silver screen. A gray or white one will not work well as the light is absorbed and retransmitted. This ruins the polarization so the images blend. I painted my screen on a MDF-board using acrylic silver paint and a roller. (Remember to prime twice first and sand smooth!)

8. For those who wonder how light can be circularly polarized I recommend wikipedia. Read the article on circular polarization. It's a headache but it IS real...

9. Recording your own 3D content is EASY and you only need two cameras spaced a bit apart. Tilt them slightly towards a common focus point (point of convergence) and make this point close to the object of interest so people will be able to focus on it without getting a headache.

10. NO you do not need to use any filters on the cameras when you film. You use the filters when you project the movie(s) to polarize the light so that the RealD-3D glasses can seperate the images again for your eyes.

11. The paint I used is called Liquitex Acrylic Basics Matt Silver.
