It's so that they can manufacture cheap cardboard glasses that work when 
they are folded in either direction.

Back to the newsgroup, using these glasses and a couple of monitors, it 
should be pretty easy to make a cheap, fixed-view holo tank with about 
$100 worth of optics*.  Put the monitors such that their faces are at 
right angles to each other.  Cover each with a polarizing filter.  Put a 
half-silvered mirror at 45 degrees between the faces of the monitors.  Put 
on the glasses and look at one monitor through the mirror and one monitor 
reflected off the mirror.

*Prices are estimated from the Edmund catalog.  I don't endorse them or 
assert that they are particularly cheap; it's just that I cleaned my desk 
yesterday and found a catalog.
