A while back, we did a post about holographic text messages viewed on iPhone. It turned out that it was a digitally-altered video for Google’s new "Mobile Phone Tricks" contest featured on YouTube.
See video below
iPhone has no capability to produce 3D holograms but it can display an optical illusion of a hologram.
iHologram – iPhone application from David OReilly on Vimeo.
This is the real deal; this illusion is created using Anamorphosis.
Also, this illusion adjusts while iPhone is being rotated; this cool effect relies on the accelerometer and the iHologram software. But you have to look at it from a 45-degree angle.
