Not only it does not bother me, I also find it very impressive in 3d.

Sometime back John R presented a theory regarding people's reaction in 3d
and how some people see the hyperstereo effect and deviations from ortho
viewing more readily than others.  I forget the detatials but he somehow 
related this to the variation in people's reaction when exposed to stereo
for the first time.

This has always been a big puzzle for me.  Why do people react so
differently when they see a stereo image?  Why are some people more
impressed or excited than others?  Why do I find 3d so fascinating while my
wife does not care?  (she has passed the classic stereopsis tests but it
takes her longer to "see" 3d and sometimes she cannot tell the difference
between a 3d image and the same image in 2d like in some Keystone cards)

I would like to connect this to other observations, like people's reactions
to hyperstereo, frozen action, etc.  I would like to realate people's
excitement about 3d with their reactions/appreciation of different forms of
3d or different viewing conditions.

Any thoughts?
