Essentially the app enables the user to view a video on screen, but becomes immersive in that when you turn the screen in any direction, the moving image on screen will pan in that direction.
It is best to see a demo of the video (below) or download the app to test free to see what it can do.
It left me thinking how great it would be to have the app change the stereo panning of the audio - as well as the vision - based on where in the "image" you were "looking". The experience at the moment, while somewhat immersive, is still quite one-dimensional - something that stereo panning could assist with overcoming.
Imagine seeing an image of a truck pass by on screen, you could hear it approach on the right and move to the left of your screen as the sound would pass from right to left also. Then if you move the screen to the left to focus on the truck, the object now in the centre of your screen, the sound of the truck would also be moved to the centre.
Technically this would be a huge feat, but surely not too far off...
