Headache box
These flat panel 3D screens are nothing but headache boxes. The 3D is achieved by first showing the frame for the left eye, then the frame for the right, back and forth lots of times. Unless they have fixed the 'switch' rate, or whatever you call the time it takes to go from right to left and back, then no dice. On the versions that I saw last year the switch was much too slow and though it did appear to be 3D (which was cool), you couldn't look for more than a few seconds without overloading your vision and shutting your eyes in pain.
