Three years ago, I could handle the amount of sunlight that came through the upper windows above my main windows. A year ago, I couldn't, so I put in mini-blinds on those. Now even that is bright enough to bother me (even at night, just from the moonlight), hence the line of thinking. Maybe it's just me.

Translucency? (Score:5, Interesting)
Re:Translucency? (Score:5, Insightful)
Another similar thing is using two layers of linearly-polarized glass. Hold one layer fixed, and rotate the other layer to go from almost full transparency to almost full opacity.
There is a company that sells airline windows like this, and it would be pretty trivial to wire a motor to turn the layer appropriately, or even automatically to keep room brightness constant.
Re:Translucency? (Score:5, Interesting)
They work like this:
1. Plasma backlight source provides whitish illumination.
2. Red, Green, and Blue subpixel LCDs sandwiched between two layers of glass selectively obstruct this light to either pass through easily at one of these colors (the three together perceived as white) or block it out.
3. User perceives cohesive image.
This is grossly oversimplified, others (or googling or howstuffworks) can expound on the details.
Now, if the backlight and its reflectors were removed, you'd only be seeing light coming through from whatever sources lay beyond it; overlaid on a window the natural light would be used, though probably inefficiently (normal LCDs depend on polarization for crisp presentation, some natural bleed would probably result from other sources).
I'm probably wrong. But I'm also done.

Here's a suggestion, follow electrical codes. (Score:5, Informative)
Dont burn your house down by rigging this up in a way where 120V power cords are running inside your walls. (I realize the page author does not have this.) If you use 120V wiring inside a wall that is not in an NEC approved manner, and your house burns down, you might be liable.
This includes not being able to have an outlet mounted inside a wall nearby the frame, in a permanently inaccessible location. No, the fact that you can remove drywall to access it does not make it accessible. Now, maybe if the entire frame swung open on recessed hinges to a finished space with a normally mounted outlet, OK. But best ask the inspector.
Many people will say "Ahh but this is low voltage power wiring" so, there isn't much danger. True, for DVI video signalling, but what about powering the backlighting?
But when the voltage is low, the current is high, and the potential is still there to create heat.
For example. You've probably got some big-ass wires carrying 100 amp or 200 amp service into your house. But if you go out to the power pole, you'll see the transformer which feeds your big wires has a extremely tiny wire getting it's power from the overhead lines. At the high voltages of transmission lines, small wires easily carry the small currents. At the low voltages going into your house, big wires carry the larger currents. Whats the same? The amount of power being carried.
So never assume stuffing 12V cords through a wall is safe just because the voltage is so low. How much power is involved?
