Mod parent up. Note that this is using the camera on the Wiimote to sense the position (not the accelerometer). There are multiple advantages to this: 1) It's operating much faster than 60hz (much less latency than webcams). 2) It's already detecting the position of the brightest points (no additional image processing needed). 3) Since the Wiimote is wireless, you can easily position it anywhere. 4) Since it is Bluetooth, you can interface it easily with many devices. 5) You're not making the conductor hold the Wiimote.
All you'd need to do is to paint or cover the baton tip with IR retroreflective material, and perhaps add some IR LEDs around the Wiimote sensor. This should make the baton tip stand out. You may still get several reflections, but software should be able to sort out which is the right one. Alternately, you can use a baton with an IR LED in the tip, if the conductor is willing.
As far as output, I've got my own idea: the basic theme is to use 4 tactile devices (such as piezos) that indicate when the baton hits the respective quadrant (up/down/left/right, with some quadrants missing according to the time, and some modifications necessary for less common signatures). For seated musicians, you can use a chair pad. For standing ones, a floor pad might work better. Or you can also use various kinds of garments (glove, arm strap, belly strap, or any combination). However you wish to apply the 4 tactile devices, the system should be able to work with it. It may make sense to rotate the up/down/left/right "compass" 45 degrees either way for better sensitivity (for the chair or floor pads, for instance).
With enough viewing angles, you get focal depth. That's what focus is, after all: bending the rays from the desired angles to meet your retinas. The question, of course, is "what is enough?" It's actually more about the density (how many differently-angled rays are hitting your pupils?) than the absolute number.

My first thought, upon seeing the question "Is it time to stop spending billions on obsolete aircraft?" is that the military would say "Yes, let's instead spend billions on new types of drones to replace those obsolete aircraft." (Of course, they'd sell off those "obsolete" aircraft to other countries, which would then create the need for more advanced aircraft locally.)
But imagine instead of we reversed the amounts that we spend on war vs. peace. In various places, Americans (or Westerners in general) are hated because we go in there with bombs, tear apart what little stability there may have been, then make a lame attempt to put a little stability back in there before mostly abandoning the area. This is followed up by various "terrorist organizations" putting in a stronger effort to rebuild the place, thereby ingratiating themselves locally and creating more followers in the process.
I suppose many people (ie, congressmen) have a hard time getting past issues of spending at home vs. spending abroad, and of course there's the issue of the tremendous waste (fraud) that happens when governments send money abroad on rebuilding projects. Neither of these things suggest that rebuilding efforts are a bad idea, but they both emphasize that it must be done very carefully, with lots of supervision and analysis to see that it is effective. The same applies to pretty much anything government does (and, of course, someone needs to keep an eye on the amount of money spent on supervision, etc.).
It's hard to keep a straight line of thinking when there are so many ways that things tend to go wrong...

Lots of NYC buildings are heated by centralized steam or hot water systems. Most of them have only a single thermostat for the whole system. In an individual apartment, the typical way to adjust temperature in the winter is to crack open a window when it gets too hot. This is because an old-fashioned steam radiator is either on or off - it offers no in-between setting. It is possible to retrofit radiators with thermostatic controls, but this just isn't done very much (despite the fact that it typically does save the building owner money). In addition, some rooms are heated by pipes without any available controls. The only way to adjust their heat output is to put insulation around them partly. And occasionally, some idiot will leave the boiler room door open, and since that's where the thermostat is located, the heat will run continuously.
You can make an accurate estimation for a given system. However, everyone else's PC and network environment will be significantly differently from that system. Even things that you think might be predictable can take unpredictably long, given the "right" setup.
Of course, sometimes it's just due to bad programming.
A car (or any high tech product) designed and built by engineers is not suitable for the masses, at least on the first revision. You need a bunch of "real people" using it before you can figure out all the "user interface issues". And I'm not trying to be an elitist; it's just that everyone does "think different(ly)", so this needs to be taken into consideration, which doesn't usually happen when there's only a like-minded group of people working on the project.
If we could make displays at the same resolutions that we make image sensors, then it would be quite easy to make the display, since it would operate just like a Lytro except in reverse (the Lytro uses a microlens array in front of a regular high resolution image sensor).
Now, performing the computations to know what to display, that's another story. Of course, you could just display the data from the Lytro camera directly.
Rather than have all these individual routers competing for air space with each other, it would be even better if they cooperated with each other to route packets and let clients roam from one to another.
Just like we graduated from lots of individual BBS's to the Internet, we need to make similar progress at the "consumer" end.
The technology is already present; all that's needed is support.
So you'll print something, then have a robotic arm remove the finished product and place it in the unprinter, where it becomes a filament that feeds back to the printer? That's even better than the printer-paper shredder combo I've been hearing about. I suppose it will still need energy input.
Say, I've got a black box sitting here that does all that, no energy input required. Except you can't look in to see the inner works, because that would break the loop. But it will definitely manufacture anything you can possibly imagine, then recycle it back into the stuff that dreams are made of.
I can think of many uses, assuming it's paired with a system for figuring out what you're looking at: - nanny device (think of the children) - automatic censorship device (nothing to see here; move along) - DRM (the MPAA says you really can't watch this) - court-ordered anti-stalker protection - witness protection program...
It is possible to have a display on your cornea that can show images you can focus on. However, it would work differently than other displays.
Once light is at your cornea, a pixel corresponds to a direction instead of a location. That is, for far away objects, all the rays coming from one point (location) enter your cornea as rays traveling in the same direction; it doesn't matter where they enter. For objects that are closer than "very far away", they produce a bundle of rays that are slightly diverging as they enter your cornea. In either case, your eye converges these rays to meet at a given point on your retina.
Thus for a display on your cornea to work, it has to be able to send out distinct light ray bundles in different directions, with each direction corresponding to a different logical pixel that you'd perceive spatially.
Figure out how to actually do that, and the world will beat a path to your door.

Indeed. Just the other day, I spotted a #7F7F7F, and knew right away I was looking at a fake.

Who's a cheater, when everyone has their own rules? Therein, I think, lies the real problem.
And banning is so easy, a child (with the right equipment) can do it. But that's usually considered against the rules (unless you wear a badge).
A big problem with that world is that it takes a lot of drudgery just to maintain your stats, so there's little time left to actually do fun stuff.
Transplant? That's old-school tech. Needs nasty immune-suppressing drugs. The latest thing is to print a new hand using your own stem cells.
Okay, maybe a few years off yet. But I expect to see it in my lifetime.

In addition, get a stand for the laptop, so that its screen is level(er) with the big one.
