- I think I'm confused, Steve. Accepting that there are some (very few)
- 3D displays (such as the image pumped through the air by a loudspeaker
- that I mentioned last week, and 3D scanned plastic), I don't understand
- the difference between stereo and 3D in your last sentence.

- I saw superb stereo pictures via two slide projectors, each with
- a polarizing filter and the audience wearing matching neutral polarizing
- filters last year in Europe. I have been assured that a similar
- setup with video projectors has been tried and worked - I can't get
- hold of a second projector to try it out - has anyone else?
