@JDy80: The problem with the white iPhone 4 isn't the home button matching.

@Darth Meow 504: circular and linear polarized light both have the same problem - you have to polarize pixels, and that's hard to do because they are small and numerous. Adding polarization is especially problematic when the viewing technology already has two layers of polarization.

@Nick2: I agree that the goal is not necessarily to kill some people. But I think it is more complex than that and it won't work out well for the perps.

@TheUltra: Everybody who likes 3D would prefer to skip the glasses! But some tech takes a long time to mature. I think that your prediction of parallax barrier being perfected in a year is way optimistic. Sure would be nice though.

@Darth Meow 504: It is possible to use polarized light for projection TVs now. You just need two expensive projectors instead of one. Or redesign the projector to have a rotating polarized filter carefully synched so that you only get light through when the angle is perfect.

@dswatson83: There are plenty of us, but what's the point of arguing? 3D lovers love it. Haters hate it. We won't be convincing each other any time soon!

@Hiphopopotamus: Sports fans who have actually tried it seem to agree with you that the experience is good.

@Ryououki: Same for me!

@richterbelmont: Unfortunately, these won't work with a 3D TV

@domhnall: Well, I smiled at the joke. :-)

@oldmac31310: Why bother with the fake stuff?

@hurbieta: Yeah, USB extension for anyone brave/foolhardy enough to use this.

@rnoyfb: OK! Sapping is ancient, but the word was coined more recently by the French. I appreciate the correction!

@HektikLyfe: The Haunted Mansion is more of a classic Pepper's Ghost - they built an entire second ballroom that contains the ghost figures reflected in the glass. The scale is huge, but implementation simple.

@Mike43110: "At microscopic level, we always work in nm"

@tomsomething: "What about America's pound? What's our reference for that?"

@jepzilla: I don't think that this is a coincidence. There must be some sort of natural law attracting cruise ships to explosive-laden harbors. This is a job for Stephen Hawking!

@jepzilla: Digging under enemy fortifications goes back a long way. The Assyrian Army in the early 7th Century B.C. coined a word for it - "sapping". As soon as explosives became available to combatants, sappers would have adopted them.

@GoSailing: Evodico's criticism is valid.

@HektikLyfe: Yes, it is called the Mystery Lodge. It is a slightly higher-tech version of the very old Pepper's Ghost illusion, a giant version of which is used in the Disney Haunted Mansion ballroom scene.
