This is from Macenstein. It's a 3D looking video of a Felix-like creature walking aimlessly around the screen.
As you rotate the iPhone, it manages to keep the 3D look and feel. In the video, the iPhone is on the surface but yet when you tilt the screen, you can still see the 3D effect. Awesome!
iHologram - iPhone application from David OReilly on Vimeo.
I don't know if we'll ever see it in the app store or if its just a demo.
Have a great weekend!
