    Wired and optical technologies will ever be superior to wireless, by the simple fact that they're essentially 1D lines running through 3D space, whereas a typical wireless signal is a 3D signal in 3D space - a single frequency gives a fixed bandwidth to a single user in a given ~volume~.

    You know your rod cells are sensitive through the blue range, right? In fact, they're not sensitive in the low frequency range - a blue filter would have less effect at night than during the day as you wouldn't be losing the 'red' range (as you aren't seeing that anyways if you're relying entirely on rod cells anyways).

    Vision is a logarithmic type response - losing half or three quarters of available light is only "one or two stops". If you're at an "adequate vision" status, it won't suddenly drop to "OMG IM BLIND WTFBBQ", but rather "not quite as adequate as before but still mostly adequate vision" status.

    Finally, the rats (or people if so treated) would only have to worry about this if the cornea, lens, or humors of the eye became blue.

    Correction: LCD TVs almost always have input lag. They tend to do a lot more signal processing than a typical LCD monitor.

    A friend of mine got an LCD TV and hooked it to a Xbox360, with audio going through the TV, and to an external sound system through a different connection. You could actually hear the delay that the processing was adding - every sharp sound seemed to have an echo, and smooth sounds sounded... strange. If you turned off the TV's sound, the effect vanished. The TV is adding delay to the audio signal so that it's in sync with the video. And this is common for all sorts of "native resolution" type displays (ie anything not CRT) - plasma, DLP, LCD projectors, etc. It's often part of the rescaling/deinterlacing/quality enhancement system.

    (Note that the absence of this effect does not mean the absence of input lag, as not all TVs will bother delaying the audio to resync it with the video)

    On the other hand, SOME monitors like my own Viewsonic VX922 add little or no delay to the input. Dual head comparisons with CRTs, done by myself and others, have shown that the VX922 adds less than a frame of delay to the image, with only the occasional kick to 1 frame of delay (say 1 in 10 or less). Granted, of course, not all monitors are of this quality...but I have yet to see a non-CRT TV performing like that.

    All of this makes sense when you think about it from the manufacturer's point of view.. if the audio is resync'd, does the TV viewer really care if the DVD/broadcast show is delayed by a few milliseconds? Versus monitors, which are usually used interactively, where such lag might be noticed.

    Finally, regarding lag to colocated servers with your ISP: That 13ms ping you're seeing is for default size packets (56 bytes of payload for Linux, 32 for windows). Consider that this .. lunacy would NOT be sending tiny packets, but rather a heavy stream of large packets. It's NOT going to be best case latency.
