Remember when you were told (if you're an SF fan, that is, and talking to somebody who likes to pooh-pooh SF and tell you everything is 1000 yeas in the future) that holograms were never going to happen because they have no foundation in real science?
Well, just now and again the SF fan gets the last laugh. And I'm chortling in large amounts of glee. And I haven't even opened the Father O'Leary's yet.
This here is something called Hatsune Miku. She (it?) is an anime pop star. It's a hologram that performs with a live band. Onstage. Live, in front of a live audience that's looking at the performance from every angle. So there's no way to fake it -- and why would you want to? Charlatanism is not what this is abut. It's just about a band on tour, and they animated their icon.
Now, anime isn't my thing -- and for somebody who grew up on Marineboy and Gigantor the Space Age Robot I say that with all due fervor and a couple of shudders. To me, the fascination of the Histune Miku hologram isn't any interest in the ainme popstar. But ... golly, that could be a hologram of ... anything. Anyone.
It could be the computer interfaces you saw in IRON MAN! What I see in this tale of Hatsune Miku is that the SF fans get the last laugh. Holographs work, and they work now, not in 1000 years.
And I think R2D2's horizontal hold might have been on the fritz:
...because out holographs look a lot better than the ones they were predicting in 1977!
LEIA: Help me, Obiwan Kenobi, you're my only hope!
OBIWAN: Damnit, the quality on this is crap. Can't you adjust it?
LUKE: I dunno. Let me have a go. (Kneels beside Artoo and starts fiddling)
R2D2: Beep! Squaaaaaw! Weeeedle ... wooosh ...awwwwwh.
LUKE: Does that look any better? I can't see it from here.
OBIWAN: Try adjusting the vertical hold.
LUKE: Okay, gimme a second here...
LEIA: I said, help me, Obiwan Kenobi, dadblast it, you're my only hope!"
LUKE: What's she talking about?
OBIWAN: She said something about some secret plans. I wasn't listening, I was trying to figure out why the playback's such crap. Any joy with the vertical hold?
R2D2: SQUAAAAAK! Weeble-beeble tooleoodleoodle ... (Subtitled into English: "Forget the goddamned playback quality and listen to the message, you brainless apes!")
See what I mean?! There's one in the eye for the guys who like to pooh-pooh SF
