 I am amused - i.e. find it comical! - when projectionists
 claim they can detect and correct misalignments during a stereo 
 projection *without* looking over their glasses... I think this

Well I, for one, can certainly _detect_ misalignment of various flavours
through my polarising glasses, though I look over them to make the
adjustment... Does this mean that I agree, or disagree with Dr T? :-)
