Post Holografic technology how far is it?

Now i have seen some pretty impressive holografic technology amongst others in this Gorillazs concert
http://www.youtube.com/watch?v=G-AhYnjKEzs

Now while i may not be the biggest fan of Yu-Gi-Oh i do like the way they play the game in the anime whit portable holographic projectors that you can carry around your wrist.
So my question is how far along is Holographic technology and when can we might start thinking of such a technology becoming something the average John and Jane Do can afford?

I don't think it will be holografic technology that is going to bring us to a 3D media world, however light field manipulating devices (similar to what we already can do with synthetic aperture radar) looks more promissing and I wouldn't be surprised if they become a house hold product within a couple of decades.

*holographic*

That is all.
Some would insinuate that being drunk at 9 in the morning to be signs of serious issues.
Me? I'd insinuate it as signs of no plans and a refrigerator full of Whiskey and Guinness.

Contrary to popular belief, full-immersion holographic sex will not destroy society.

What exactly did you have in mind? Creating holographic images of relatively negligent quality is not especially difficult, and hasn't been for a considerable length of time with modern technology. I mean,lasers and suchlike aren't all that expensive these days. And supposing that at some point in the not-too-distant future (as you allude to); there is some form of large scale use for holograms, then there would no doubt be multiple burgeoning economies in recent times (such as China and India) who would seize the opportunity (so to speak) to lower the cost of the production of those holograms.

But unfortunately, rather like almost any other technological advance that has popular significance among certain people, or "buzzword", gee-whizz novelty in it, the term "holografic" [sic], carries various distinctive assumptions within it, which are in fact nonsense, and more often than not, do not match the reality of the matter. Did you ever note the fact that so-called "normal" or "visible light" holograms , such as the ones that are displayed on modern credit and debit-cards , appear to have luminous (multi)-colour effects? Indeed, necessarily so . . . holograms per se rely upon wave-interference for them to perform their desired functions properly. However, that also necessitates that there is a different diffraction for disparate wavelengths, and hence so called "rainbow effects"â„¢. And also, it's a given in the case of holographic imagery that you are trying to generate a 3-dimensional image (3D), from a 2D surface, as you can see in that video. But 3D constructs obviously have volume . . . and as a consequence, at least with current technology, it's always going to be comparatively low-resolution, when contrasted against 2D images, such as 1080p YouTube videos.

Of course, I understand and fully acknowledge that in a lot of science-fiction worlds , most of which are constructed (written) by people who would very likely not know real science if it bit them in the behind , seem to be fixated with the concept of holographic images and interfaces, as their writers surely are. And while it most definitely is a physical possibility, it is not a mystical panacea. The idea itself is not magic, but rather enciphering. "Memory"-technology to date, is dependent on 2D or very fine layers-access. Theoretically, it may be possible for us to reverse the holographic generational process, with the utilization of photoreceptive chemistry (of the kind used in LED sensors and such), in 3 spatial dimensions, and then (re)produce our addressable surface or platform in 2D . . . and then use whatever holographic techniques are readily available to map out our addressed 2D image in 3D space, and the original could be read out with a fairly simple laser, or other optical array. The magic is simply the ability to utilize an unmapped-3D-space to correspond to a rigidly-mapped 2D space. Admittedly, it sounds very good (and fascinating) , and it's not inconceivable that some brilliant engineer or technician somewhere, some day, will go about figuring how to make it work efficiently , but the engineering and computing challenges in such an enterprise would be truculent indeed! And among many other problems, the recording material itself, will have to have a minimal or rigorously calculated distortion of light, and the recording process in itself would be required to intercept light to record the wave interference, but NOT to such a degree that it would cause interference of the adjacent interference patterns themselves.

Perhaps I'm just ignorant of regular human interactions, but that aside: what do you think you would be able to do with the technology? There are serious physical limitations and restrictions on what is possible (or testable) even theoretically, and even more so practically. But once again, on small-scale resolutions (the equivalent of 200-400p or something similar), it genuinely isn't all that difficult to achieve. There has just been no reason thus far to accept that such technologies could create profits to such a degree that large business and corporate entities could justify creating an assembly-line somewhere, where the pieces are all stacked together in a simple, consumer-friendly package. And indeed, with the ubiquitous surge in high-resolution printers, low-resolution holograms could (very) likely be printed on transparencies, and viewed with a monochromatic light, and possibly a laser or spread-lens. The existence of commercially viable hologram-production would effectively mean there would be a need for higher-resolution printing of the aforementioned interference patterns. But that itself; is not difficult. You CD-burner can do everything required in this process, and contains within it all of the necessary hardware and is close to , if not, actually at , the resolution required! You could burn the specified interference pattern (whatever it may be), onto a disk, hit with a sufficiently powerful laser beam, and then you've formed a holographic image, effectively.

What is it that would justify making it available to almost everyone? I mean, I could very probably (given a considerable number of months, though); create something just like what I've described above, almost from scratch. But you already can purchase "kits", of limited usage, to create holograms with. But it will be at a hideous cost, I would imagine, at least for the time being. I might invest in one at some point, if I can find both time and will power to do so.

I was going to quote it if you hadn't pointed it out already.
Why does my life have to be so small
And death is forever
And does forever have a life to call its own?
Don't give me an answer cause you only know
As much as I know
Unless you've been there once
And I hardly think so

It would probably be the most logical sex one could ever have......
There is still light in the 'Earthly' darkness. Finding light in the darkness can be more satisfying than merely seeing the glaring light of our sun. It gives us a better understanding of light and a deeper understanding of our universe.
