Use circular polarized filters, not planar polarized.  That way the
viewers' heads can be other than vertical without L-R image
bleeding.  Our first wall was planar; our second used cilcular
and was much more acceptable.

If using front projection, remember the wall must be of a material
that preserves polarization - Harkness Hall do a suitable range.

Beware of the plane of polarization within LCD projectors - some
are suitable and some are not and you can only tell by testing -
the relevant info isn't in the manuals.  We got stuffed when we
took our system to an exhibition and hired in projectors from the
same firm as we had here, and found the models we had hired were
different.  On reflection, that was while we were still using
planar polarization - maybe it's not an issue with circular.

Cheers
