Hi
Just looking at the diagrams, I don't think the glass is half-silvered
- it looks like a large sheet of Polaroid™. It only needs to polarize
the transmitted light from the vertically oriented monitor, since the
reflected light from the interface between two materials (at least one
of which has a refractive index) will be polarized in any case (that's
why your Polaroid™ sunglasses let you see below the waves...). My
physics is too rusty to remember, but I think the vertical monitor in
this case needs to be polarized vertically, since the reflected
polarized light will be horizontal.
No idea where you can buy large sheets of Polaroid™ though.
IMWBW, though...

Hi Andrew,
Just like the commercial systems, the glass is the only special piece
of kit (which can be bought separately). The LCD monitors are just set
up to display either left or right channel. If you ask me, I think
these companies are just a rip off!
