@Sid: Yep, she's Hatsune Miku.

And the video looked really great, but she looked a bit "pixelig" in HD...

i don't think it really is a hologram. i read an article somewhere which stated that real holograms (also with a glass screen) aren't possible with good frame rates yet.

it would be awesome if holograms without screens were possible. i read another article a while ago which stated that it theoretically could be possible with very strong crossing lasers that create a glowing plasma or something (i don't remember the details). sounds kind of dangerous though.

this is screen projection. its old tech. check gorillaz and madonna live from a few years ago. that was great^^

Maybe that's where the Japanese culture is superior to our in term of acceptance and candidness. We all know the polls where Japan is one of the countries most likely to accept robots with artificial intelligences into their society. In a way this is a first step towards that. Whereas in other countries, new technology is often frowned upon for a long time until it finds acceptance in mainstream culture. Especially in countries like Germany, where a lot of people like to hold on to constants, a life that never changes. Just look at all the movies where robots are the bad guys and in the end try to take over the world, yet in Japan, there are lots of animes with robots, and waddaya know, they are often one of the good guys.

Perhaps we should cut ourselfs off a slice from Japanese culture and start being happier (and less grumpy), have more acceptance (and less prejudice) and being more open to what the future holds in store for us so that one day you can enjoy having a kegger with your Robot pal in College.

@Michael: There´s a difference between a real robot and a virtual character . I would like to see a robot perform on stage, but not some projected fantasy object. Not that I agree with HeelX all over, it's also about the experience. This show is pretty scarce, only one or two characters. But if it became more of a movie, I would likely enjoy it much more.

Yeah, but there are also people who pay for porn.

Here's a slightly more advanced hologram:

Do the Gorillaz perform live?

So, you would never purchase a DVD of a rock concert? You would never see something like Pink Floyd's The Wall? These are all "virtual". What you are paying for is the experience, the entertainment. It is not that much different than going to a movie, except there would be more crowd participation. And while people singing live (lip-syncing?) let's you actually see the people at work, there were people at work that created the experience of these virtual concerts. Someone had to create the models, capture the animation data, skin the model for animation, texture it, etc. Don't they deserve a paycheck?

@RealSerious3D: Those are lit pingpong balls on wires. That's not really advanced just a nice trick, but not very usable.
