    Except that there is one problem -- when your left eye is looking at the right half of the screen, your right eye is looking there, too!!

    No, because your right eye is wearing a polarizer that blacks out the right half of the screen and lets it see only the left half. See figure 3.

    I'd hate to have to peel off the melted cellophane from the LCD.

    The motion technique is interesting but it only works reasonably well for objects close to the middleground. Objects far from or close to the viewpoint will usually look too jittery to be perceived as 3D.

  4. Why do I need an LCD screen at all? by raehl · · Score: 4, Insightful

    Couldn't I just take a regular old CRT monotir, put celophane over the right half to polarize it, then put another pice of celophane over the left half, but rotated 90 degrees, and still end up with two halves of a monitor polarized 90 degrees from each other?
