I've been to movies with polaroid-glass 3D, and they never quite work; you
always get a headache trying to keep both eyes locked on the scene; it was
that way 15-20 years ago, is still that way now. Does anyone know why that
happens, and whether it's intrinsic, or something that could in principle be
fixed but will be unaffordable for the near future, or something that will
likely be fixed with foreseeable progress?
