Yes, I've thought about the possibility of the two sheets not having
identical orientation. But it is also possible the light coming off the
objects is differently polarized in different directions, no? The
parallax of polarization, as it were. Blink comparison left-right does
clearly show me I'm getting different apparent reflection.
The test would appear to be to get a big sheet of Polaroid and hold it
flat while I look at such an object with both eyes. Even if it is
attributable to "mis" orientation, I think it's cool and I bet the
information has value.
