I've been trying to wrap my head around how 3d glasses work. I think I'm finally there, but it took making this diagram to get to the bottom of it (although it really confounded things for a bit since my monitor's screen - one of the subjects in my experiment - has a polarized screen).

If you can get your hands on a pair ($16 and they usually come with a free screening of a Pixar or James Cameron movie) they're really fun to play with. Especially if you take the lenses out of the frames.

The ones I have are from RealD 3D who uses circularly polarized lenses instead of linear (which was the source of much of my confusion). Try standing in front of a mirror with the glasses on and alternate closing your left and right eye while looking at you your eyes. Spooky!

Here is a photo of two lenses (1 horizontal over 2 vertical taped to the top of my computer) with diagram:

Explanation:
#1 Horizontal lens on top of #2 Vertical lens

• R1: 2VS - Little or no effect
• R2: 2VM - Little or no effect
• R3: 1HS - Little or no effect
• R4: 1HM - No light passes through
• R5: 1HS over 2VS - No light passes through
• R6: 1HM over 2VM - No light passes through

Key: 2VM = Lens side 2, vertically aligned, viewing monitor

James Cameron's new movie Avatar might have the largest budget in the history of movie making that includes $150 million for marketing alone.

So what font did they choose to represent their vision and set the tone of the film? Papyrus.

Papyrus.

Wow. That's. just. awful.

It's all over the trailer too:

**UPDATE**
It looks like the font used in the movie is actually a hand-drawn custom font that just happens to look EXACTLY like Papyrus.

(that's Papyrus in red on top of the movie font)

I think this is actually worse than using Papyrus itself. With $150 million dollars, they came up with that.

It doesn't only look exactly like Papyrus, it's clearly based on it too. Look at this close up of the 'V'. The awful jagged edges of Papyrus follow the contours of the movie font perfectly.

Absolutely indefensible.
