Why LCD only? (Score 1)

Essentially, the technology is extremely simple. It redirects the odd scanlines to your left eye and the even scanlines to your right eye, allowing your two eyes to view slightly different images at the same time (the sole requirement for being able to display images "in 3d"). Since this is done with a permanent lens, the lens must line up with the pixels on the screen EXACTLY. On an LCD display, the pixels never move, so this is easy to do. On a CRT display, the pixels are not always in the same spots, so creating such a lens would be much more difficult. It's really a simple concept, and I'm surprised no one thought of it before. Regardless, I can't wait for the day I can play Quake 3 in 3d.
