Yes and no...

	There have been studies where they stuck glasses on 
people (college students despirate for money no doubt) 
which flipped their field of view upside down.  After a few 
hours - nothing.  But after a few days... they saw 
everything normally through the glasses.  Their brains were 
plastic enough to compensate and 'fix' the way they saw 
things.  Of course, when they finally took the glasses off, 
they saw everything upside down for a few days again.  :)

	So - yes, watching things which disconnect the way 
the world LOOKS from how your brain expects it to look can 
change the way your brain works.  But...
	1)  Effect took several days to take.
	2)  Effect didn't last 

	Granted, the experiment isn't an exact mimic of 
watching 3D movies, but if anything it's a much more 
extreme insult and everything worked out fine.
