iHologram Looks Remarkable, but Is it Real?

Why is this any different that the effect from mach dice? If mach dice can do it, why not a 3d anim loop? The loop is so short that it would simply change the video clip loop from 1 of say 8 loops. Or, maybe it's generated on the fly like a video game 3d character.
The accelerometer detects movement in any direction, so it seems plausible that it lay on a flat surface.

Fake!
I would vote for Fake, but nice job with the choreography! The animation would have been done before hand, I dont doubt the video having been played on an iphone. It seems like compositing the screen would be way more work then it would have been worth.

I'm sure it is real, it looks like a rendered 3D application with a little optical illusion. It is neat that the iPhone has such decent 3D acceleration, however.
Whether real in this case or not, it's still possible
Could easily be real.
This kind of thing is being done on many devices. It's the latest thing fpr R&D labs to play with, and there is even public code for playing with Wii sticks this way on a PC. Google around for it.
A common example is to have the perspective change as you move the screen around, such that you can look "behind" objects.
So you'd start with the phone right in front of you and you'd click a button to reset the scene as straight on. Then as you move the phone up/down or left/right, the scene changes accordingly.
E.g. move it up, and you can look "under" and behind an object in space.

well its great and all but sorry its not real
NOT REAL
And for one reason, when your turn your iPhone/iPod touch the screens color/brightness/tone changes, just look at a picture of on your phone and then rotate it like it is in the video, the colors change when you view it at different angles and in the video there is no changing at all!
Case Closed

I was (and mostly am) convinced this is a fake. The rotational data is too quick to respond. The accelerometer is too laggy for real-time input as sharp as this app showed, and that's counting the possibility this was shot on a table sufficiently angled to get the accelerometer working.
HOWEVER,
What if they were taking camera data and tracking with it like an optical mouse or PS3's Eye of Judgement?
If they're not using the camera, this certainly points to the possibility. I still vote After Effects or Shake, even though it'd take some skilled compositing to not kill the fingerprints and reflections.

i am seriously offended by some peoples comments here.
People actually think, this can be an ACTUAL hologram? come on you guys... theres no way light can be stoped at a fixed point unless theres something on its path..... this is what we called [h2] Optical Illusion!!!!![/h2]
its just lije those street painters , where if you look from a specific angle, the drawing looks 3d, buts actually flat!, just like this thing!!! its a flat surface... just it rotates the object!! and no, its not a flat surface... its even almost impossible to have a flat surface where the iphone wont be its slightest angle

download "rainstick" and you'll see that the background can change with you rotating the phone, and you'll see how good and sensitive the iPhone is. You'll also notice how close to a zero angle you can get for it to still work...!
I don't think people are arguing that it's a real hologram, but whether or not it's a real program. I think some people think it's an actual program that's capable of rendering a simple animation in different perspectives based on the position of the device, giving the illusion of a hologram, and other people think the iPhone/Touch isn't capable of doing that and that the video is completely faked. I'm not getting the sense that anyone thinks the program, if it is real (and I think it is), is actually projecting a holographic image in any way.
I don't agree with this at all. Having tried apps that rely heavily on the accelerometer, such as Labyrinth, I'm convinced that the accelerometer has plenty speed, resolution, and sensitivity to do what's shown in the video. No problem.
Exactly - if the original poster would go to the artist's page (see my earlier post - oh heck, here's the link http://www.davidoreilly.com/blog/2008/08/ihologram/ ), he describes the methodology used to simulate 3 dimensional art.
I still haven't heard back from the artist. I am not sure which direction to lean. He's very talented with art and obviously knows how to make movies. With his pitch at the end of the page indicating he isn't very good with programming it makes me wonder more if he's put this together hoping to get a programmer interested in developing this for him... who knows.
I just watched the video of the hologram, and Mach dice. I then bought Mach dice and compared it to the video, it looked even better so maybe the hologram would look better? I don't know but it may or may not be real but could you imagine how great of things this could bring, could you imagine a holographic cuberunner or for music show your album cover, or a book like that, it's be revolutionary!!
Yes, you can
You can detect rotation on the iPhone with the accelerometer, the question is how accurate it is to implement that thing. Constant rotation produces centrifugal forces, which are registered by the X and Y accelerometer (I have verified that). I assume that the accelerometer is not built in the center of masses of the device. An example, if X=0.1, and Y=0, there is no rotation, only translation, but if X=0.1 and Y=0.1, then you have an ambiguity, it could be just linear acceleration or constant rotation. These guys had just considered the last case. Then, it is a question of tuning up the output from X and Y to related centrifugal force with angle. I hope that video is real and that is the explanation, because I am going to implement it!
Upd1: I have thought a little bit about that, and although my example is not accurate, the trick could go in that direction.
Upd2: But the tilted table seems to be a better explanation.
