When I saw inside the VPL eyephones, it seemed to me that the main problem 
was the size of the triads.  They were big, big enough to be perceived as 
objects in their own right, which interfered with their contribution to 
the overall picture.  There was a scrim in front of the LCD to blur them 
out a bit, but of course then you could see the blurring.

So, I don't think that the problem is NTSC versus RGB but rather just the 
inherent resolution of the device.  (Yes, I know all about NTSC and its 
shortcomings.)

We really need more pixels on the screens.  This can be done one of two 
ways--by making the screens denser or by making them bigger and changing 
the optics.  Does anybody know what size the LCD's in the eyephones are?  
The biggest I have seen in consumer electronics is 4 inches, in the Sony 
LCD TV and the Atari Lynx portable video game.  The latter is cheaper and 
might be useful if one could figure out the driver circuitry.
