Steve, I did realized this was all he was doing with the use of the colored arrows, it's just the whole red/green glasses thing has practically grown into a cultural icon by this point and it really makes my skin crawl because it's just so wrong, like calling a projector a "camera."
I just went to Richard's Franklin Design link in the thread about silver screen paint and here's how this cutting edge cinema design company on their home page represents 3D: I mean really -- see what I mean?! It's just so weird because even if people were too young to recall ALL the 3D movies in the 50s, certainly they are old enough to remember the over/under stuff from the 80s and NONE of them, not a single one ever used anaglyphic. Now unless the ONLY 3D films these people saw were the two Black & White titles CREATURE and OUTER SPACE that Universal released almost as a joke in VERY limited specialty runs in anglyphic, it's a mystery to me how this could ever have morphed into what EVERYONE now claims was how the "old" 3D movies were shown. It just makes no sense to me how we got to this persistant global error.
As for eye strain, yes in nature you focus at the same point you converge....we get that, but as Manny says, that doesn't seem to be a major issue for most people when all other parameters are where they should be. I contend that well-planned/well executed stereo cinematograph with CORRECT, smooth convergence transitions from shot to shot is the BIGGEST factor in not abusing the viewers' eyeballs, much moreso I think than focus/convergence point discrepencies.
I was a pre-teen when I saw almost all of those 50s films and never, EVER got even the slightest discomfort, headaches, eye-strain, etc. I did see them in a flagship theatre on Long Island which had flawless presentation all the time. I saw them all again a few years ago at Jeff Joseph's 3D World Expo at the Egyptian and again, presentation was flawless -- dual projector, so that eliminated the temporal staggering which some people seem to be very sensitive to, again, moreso than the focus/convergence issue. At the Egyptian we all watched 3 feature 3D films plus 3D shorts every day for a week. I never heard anyone complain of the so-called eye-strain.
I think the eye/brain focusing and convergence at different points is really only a mental coordination that can be easily learned. It doesn't strain eye muscles because those muscles are capable of moving the eyes and the lenses to those positions all the time. It's only the coordination of the two that is different, the muscles are not being strained. And like all coordination of muscles, it's a learned thing. If all those people who watched AVATAR are any indication, the brain seems, at least in the majority of people, capable of learning how to coordinate and synchronize those different moves and does so without too much effort or side effects.

I'm not sure about the second festival, but for the first one there were many days that we watched FIVE features in 3D, all of them included a 3D cartoon or short subject of some sort in front of them. It was watch a movie, leave the theater to get in line for the next movie, then back in again, then again, then a couple of hours break for lunch/dinner, then two more movies. While there were some days where the movie count went down to 4 or 3 or 2, this generally went on for 10 consecutive days.
Agreed - no eye strain here either.

That bugs the shit out of me. I'm almost constantly aware of it with digital 3D and even 3D TVs.
