THREE-DEE VIDEO from multiple lcd panels. Answered

This morning I was watching television and thought to myself, "Wouldn't Good Morning America be so much interesting in three dimensions? This got me thinking, and I came to this idea: what would happen if you dissected a bunch of lcd monitors, removed the backlights, and stacked them. Then, you plug all of the screens into a processor that generates an image for each screen, and have a powerful backlight to illuminate these screens. I know that it is quite a stretch, but if one could work around issues such as the amount of heat produced and the cost of production, I think this could work. I think the best bet for input would be using RGB or CKMY on multiple panels, but I am not an expert in optics or any of that. So basically, this is an outline of what would need to happen, as far as I can tell:

1. A group of LCD panels that, when in a cascade formation and are fed sufficient data, produce a three-dimensional image
2. A bright backlight that is capable of illuminating said LCD group
3. A video processor capable of sending multiple signals to the screens that would produce a three dimensional image (as stated in point 1)
4. A cooling system to maintain component functionality
5. A benefactor or deep pockets
6. Lots of spare time

If you have any ideas, please add them, I'd love to hear from the Instructables community.

why not just invent free form floating holograms?

3-D TV is here (see the news papers) if you want to wear $50 shutter glases that give you headaches if you are not in a dark room.

Better idea: Two LCD computer screens, (one vertical, one horizontal) with a plate glass beam splitter at a 45* angle in front of them. (Like this: _\I  Sorry, I can't quite do it on a keyboard.) You jigger the polarizing filters on the display and wear cheap (free) 3-D movie theater glasses that let each eye see only one screen's immage. Both screens are fed by a computer with a dual display video card. The horizontal screen needs to have its immage displayed upside-down to be right side up in the beam splitter composit.

Somewhere I heard about this system. It seems cheap enough and might be a better first comercial system.

Is anyone out there working with something like this?????
I might be willing to buy one if the price was right.
