How about the Germans???  Do they agree too?

I have to confess that I don't own a 2D projector.  All I do is stereo
slides.  If I ever want to show a 2D slide I will have to mount it
in a stereo mount and turn one side off.  Also, all my stereo slides
are in stereo mounts. I would need to remount to use 2x2 projectors.
That's the biggest dissadvantage of 2x2 projection for me:  It can
only be done with 2x2x2 slides.  But with a projector like the Brackett
Fader can show both.

Here in the USA we are in the point of linking stereo projectors like
the Brackett Fader.  I was impressed by what I saw in NSA.  You
get two of these babies and can have stereo dissolve or you can
project two stereo slides at the same time in different screens and
tell people to compare normal vs. pseudo stereo, different placements
of windows, etc., at once!  Great instructional tool!
