> The 3D projection technology has improved since the 50s, but not as much as you might think. You still have to wear glasses, but I think they're different glasses. They're not the cheesy red/green lenses but rather colorless polarized lenses. Unfortunately the colors get dimmed, but at least you're not looking at everything through red and green shades. The other problem is that the glasses get fingerprints and stuff all over them from previous patrons.

> There's a more expensive 3D projection technology around that was used for The Polar Express a few years ago. That was excellent, but 3D movies since have cut more corners. The worst situation is if a movie filmed in 2D is artificially manipulated to produce a 3D image. This process was used on the Harry Potter films, for example. It's ridiculously lame and disappointing.

I heard good things about Coraline in 3D, though I never managed to see it (nowhere near me showing it in 3D).

Incidentally, polarising computer monitors have been on the market for a year or two, and I believe TVs that don't require glasses at all have produced working prototypes, though I can't for the life of me work out how they work. Sky is intending to broadcast the 2012 Olympics in London with a 3D option, so apparently they think 3D TVs will be in homes by then...
