It looks like Mike beat Dr. T to the group's stereo hair splitter.  I
should have included the words "synthetic" or "inexpensive" when
describing Dr. L's "invention" of the polarizer.  Clearly, Land did not
invent Icelandic Spar nor was he the first to notice what it could do
(Nichol did that).

Did anyone notice that my post was not about polarizers??  It was about
color theory and perception.  I mentioned polarizers because without
them, stereo projectors might have evolved quite differently.  Oh yes,
someone in the group had asked whether polarizarion was involved with
the color from B&W effect.
