I know that field-sequential 3D systems will not will not work with HDTV, plasma, projection or LCD based television sets.

And CRT sets normally don't get much bigger than 40", am I right?

So what if a person invested in a fresnel lense based projection set-up, a do-it-yourself affair that magnifies the image from a CRT (cathode ray tube)television set by way of a fresnel lense which then projects the image onto a wall, ceiling or movie screen?

Would the field-sequential system still function properly? I mean the images are still coming from a cathode ray source, so in theory, it seems like it would work.

I've always heard that the bigger the image, the better the 3D effect. BUt we all know field-sequential requires a CRT-based signal to function poperly. So why wouldn't a frsenl lense projection from a CRT set be the ideal solution?

Here's some info I've managed to dig up regarding CRT-based fresnel lense projection:
