saw on e-bay a device that uses "shutter" glasses and a converter box to achieve 3-d effect from "any tv"-- has anybody tried one of these with a pj ???

I'll tell you how to simulate it: Cross your eyes and stand on your head. It's total BS. Shutter glasses do work, but you can't mystically add information to 2D images to make them 3D. The fact that they're making these kinds of claims makes me think they probably haven't done much at all except buy a buttload of knockoff crud and hack something together. Run. Run far.

They make these for Nvidia cards and CRT monitors

Might be considered necro-posting but I do have some experience with 3D glasses.
I would just like to add that I used these for many years with CRT monitors to play racing and flight simulators. They DO work, but you have to
1. Have the drivers installed and configured to tell your video card to alter the OpenGL and DirectX rendering for the correct Stereoscopic setup.
2. push the refresh rate above 80hz since the glasses will effectively cut that in half.
3. Have the gamma of the 3D rendering pushed up to compensate for the tinting that glasses add to the image.

I'm hoping to try my old pair of 3D glasses with my newly acquired CRT Projector sometime in the next month.

Did you ever get a chance to try this?

I've got the only pair of X-Ray glasses that actually works. I bought them when I was 13 from an ad in the back of a Fantastic Four comic book. I got lucky. The ones my friends bought didn't work. Wink

So you were a perverted little 13 year old were you? Wink

You may find the phosphor persistance with the standard CRT tubes is to slow to give a good 3D effect as compared to a CRT monitor. However who knows, you may have a fast green tube ( quick decaying phosphor, get's darker quicker ). If you do, you have really lucked out for 3D.
