With this experimental application you can see structural color
which changes according to viewer's eyes position relative to the iPhone.
Structural color means color which changes with directions of
objects or perspectives like CD or jewel beetle.
This application achieves simulating optic interference by calculating the viewer's eyes position relative to the iPhone with gyroscope and face tracking.
This application works only iPhone4/iPad2 generation or later.
