That comment isn't as intelligent as it sounds. Modern tempered glass doesn't breaky very easially, and can stand up to baseballs. And that is assuming it is even glass, some windows are actually plastic, which can be bullet proof! Patio doors wouldn't be possible without that. (Or at least not as most houses have them with a patio door installed, but no deck outside since a kid could break through regular glass and fall several floors) Modern windows are a lot more complex than glass in a frame. Fortunatly they work just like the old type, just better.
I'm not trying to imply that you can't break this glass, because you can. However you can beat a patio door with a sledge hammer and not be sure of it breaking.

This tech is nothing new. An art house exists in Europe that uses solar power and is full of windows like this. It's lcd-embedded glass. The house itself is on rails and rotates to face the sun (it's a circular house on tracks).
One cool feature the house has is everchanging antique mirrors. You know those old mirrors with random black patterns in them? These actually MOVE and change over time. There's a thin layer of bacteria that eat the substrate and move from place to place. Crazy, but interesting.

A low tech work around has been available for years. Just don't get the scratch resistant coating on your lenses, treat them like crap and they'll soon be scratched enough to be opaque. After that it's simply a matter of pointing a projection system at them.

3D from LCDs, making a VR room (Score:2)
Imaging So, first of all, IIRC, LCDs of the sort this window uses work by having the charge change the liquid crystal's polarization. If polarization is synced with the separate sheet of polarizing material it is clear, if not, then it goes opaque. So let's say the user puts on polarized contacts. Left one way, right the other, and the sheet of polarized material is removed. Then you have a "phosphor" layer in the back (OLEDs?) and a layer of this stuff in the front. The two layers are synced so that the image is refreshed at 60Hz, with two images per set. Left, right, left, right. That is then matched with the front layer which is switching polarization at 60Hz as well. Horizontal, vertical. Horizontal, vertical. So there's your 3-D.
Now let's say that the user(s) is/are being tracked by the environment (little transponders in clothes like the ones used for motion capture).
Concept Sound is ideally generated by having speaker elements built into the surfaces, with the surfaces broken up into a grid so that a sound can genuinely move from one place to another. The whole mess is wired up and driven as a phased array, where volume and frequency mix are set for each coordinate separately. Let's say a one foot grid unit, giving an "audio resolution" of one "pixel" per square foot. (Okay, so I'm working with English units instead of metric - shoot me.)
Approach One could probably get away with reduced sound resolution in the floor and ceiling. And if we're going to talk about near-present tech setups then I'ld say make the floor of "environment module" tiles of about one foot square (assuming that the user(s) wear shoes) with each module having, in addition to a speaker driver, a thermoelectric unit to make panels able to get slightly colder or hotter, a low-freq. (say 10Hz to 200Hz) vibration generator, and an ability to skew slightly.
Breakdown So, what is our gear for each tile? (Keep in mind that we're talking about buying enough gear for over four hundred tiles, so assume Jameco small wholesale order prices.)
* cheap bass speaker- $2
* thermoelectric unit - $15
* cheap mid-range/tweeter speaker set - $4
* four heavy load, fine control solenoids (for skew) - 10 x 4 = $40
(Remember that solenoid travel is about one to three millimeters, max, while cycle time can be as slow as a tenth of a second.)
* center post - $1
* ball joint for connection between center post and tile - $2
We can afford to use cheap delrin or whatever parts and just lubricate the hell out of them. Deflection is dinky, stress is all compressive, and maximum load (assuming jumping around) is what, a momentary seven or eight hundred pounds?
* underlying frame of assorted wood, glue, nails - $6
* masonite or ply tile panel - $0.5
* doped and painted fabric flooring surface - $0.5
(Probably scotch-guarded or equiv. if left painted, not my problem if turned to imaging surface)
* hunk o' cheap metal for placement between thermoelectric panel and tile underlayment - $0.1
(surely these would be bought surplus somewhere)
* wiring harness, connectors, and assembly - $8
Hey, we're assuming graduate student labor here.
Then add, say, three thousand dollars for laying in the underlying framework that the whole thing sits on (let's say a grid of 2 x 6es).
So, what's the damage? About eighty bucks per tile. For a twenty by twenty foot chamber that means four hundred tiles with, say, twenty backups for a total cost of about thirty six thousand dollars. Less then many frats spend on a holiday float. Less then a big college party. If I were in charge we'ld be buying everything at surplus (perhaps here [sciplus.com].) and could probably bring the whole floor in for fifteen to twenty thousand. Add about ten thousand for mistakes and development costs.
Electrical Power usage per tile should be about five watts[1], all of which could be run at six or nine volts (so gotta use BIG gauge wire to deal with resistance issues), for a total running load of two thousand watts (and maybe a hundred more to drive hidden fans in the walls and ceiling[2]). Let's add another couple hundred bucks for a big ol' stepdown transformer to give us all those amps of six/nine volt current.
Computation As for processing drain, well, assume thirty audio signals that just get routed around the room like sprites in an old video game. Bass/vibration and temp could each easily be one sixteen bit value. If somebody gets slick, all four solenoids could probably be one value as well, but let's assume one per solenoid. Think of it as a color video image of twenty by sixty pixels with a refresh of fifty times a second or less and it becomes obvious that the only real problem is converting that data to signals on four THOUSAND (common ground for the solenoids) wires.
Okay, now given all of this, let's say that the ceiling has no solenoids and a resolution of one tile per two square feet. The walls have no solenoids either but a one foot tile resolution. Then only have thermoelectric on one panel in ten (since heat moves mostly vertically so the implications of localized wall temps are only notable if you get really close).
So a sim handling everything but video would be using less processing power then a single PC running Doom and the whole system up to now adds up to about eighty thousand dollars. So, what is the imaging cost? I dunno. Not my yob. I'm, after all a mech guy at heart.
Final&Notes I just thought that I'ld take a few minutes to clarify what it is we're talking about here.
[1] Even more then most of this, this number has lots of handwaving in it. I suspect that solenoid usage will be weird in some way that I don't know enough to predict.
[2] Fans pushing in bits of breeze should make all sorts of weather/motion.etc. effects more convincing. Low-bandwidth, high touch. Maybe add one of those spiffy new aroma generators in each one. (I could mention stuff like aerosolized THC but I won't. Ooops! Too late, I did.)

Half-right. From the FA:
The article doesn't mention the underlying technology by name, but it's probably simply an LCD panel similar to that in a notebook display. Whether the relaxed liquid crystal strands uncurl with (white, transparent) or against (black, opaque) the plane of the polarisation filter is always just a manufacturing choice. In notebooks it can be a matter of saving power by minimising the amount of screen you need to change from the default, on average. A white-on-black character display should probably relax to black, while a black-on-white Mac-style windowed display might better relax to white. Of course I'm not claiming they always use that much logic in the decision (Apple maybe since they seem to put a lot of thought into powersaving, but more likely they just buy what's cheapest like everyone else).
The tendency of the windows in the article to relax to opacity could be thought of as a privacy feature, I suppose. It does seem odd when the device is being sold as a window that can be used as a screen, though (as opposed to the converse).

You're totally right, and the article describes this as a prototype without even an established price. Obviously for the money, whatever it may be, there are much better systems out there -- but that's when you follow the "building a shrine to your TV" model that we're all living with. Take a look around: people build whole "home theater" rooms onto their houses for this stuff, which is ridiculous. The basic M.O. here, as described in that quote from the Andersen guy, is to make the technology fit into your life better, rather that making you suffer with a hardly-really-hidden 42" screen in a colossal entertainment center around which the furniture must make its obseisance.
And yes, of course for the money you could build a nice low-profile drop-down screen. Somehow as a design choice, that wouldn't have the magic "zing" of the room going dark and the picture window turning into a screen in an instant. So nope -- not rational. (Would you want the room to darken every time you watched the 6 pm news anyway?) But it's a design approach I wouldn't mind seeing more of.

Maybe it changed depending on the light around it?
