I know the original mail was not meant seriously but your words make me 
think.

It reminds me of something I have heard about a while ago. Perhaps you 
know that extensive use of stereoscopic display devices that fool the 
human eyes by presenting selectively a different image to them (left or 
right view) will cause irritations or headaches because the neural 
patterns inside our brain are trained to change the orientations of the 
eyes to allow following an object moving in 3D space. If the neural 
patterns assume an object is changing its Z-coordinate it tries to 
adjust and fails (object goes out of focus), so it retries and all these 
retries cause the described problems.

But the more disturbing fact is that I have heard of studies reporting 
that the brain will adjust to this condition and afterwards your neural 
system for determining distances is damaged and will probably need to be 
retrained. If this is true, people who depend on this ability to work 
right (fighter pilots) should better not play their favourite ego 
shooter with LCD-shutter glasses.

Personally I am as much interested in following the latest technology 
dance as I am in finding out what changes this brings along in the way 
we perceive the world around us. It should not be for the worse.
