David OReily is without a question a skilled animator as is evident by his splash screen intro of his website.He is currently exhibiting a cutting edge application for the iPhone/iTouch which gives the illusion of a 3D image jumping off the screen. as is illustrated on the image seen here to the right.
The application (iHologram) works by assuming a constant viewing angle (35-45degrees), typical for when the device is placed on a tabletop. The 3D scene's perspective is warped using anamorphosis, the same technique used in Hans Holbein's painting The Ambassadors. This application does the exact same but updates dynamically.
David OReily discovered some poignant aspects of human brain visual interpretaion in relation to creating this remarkable application.Firstly, that there exists an average angle of view that we are most comfortable with whilst viewing motion on the iPhone (35-45 degrees).
Secondly he discovered a Rotating Grid Illusion in that a large grid seen rotating at a certain speed will appear to group itself into smaller grids, spinning independently.
He put those ideas together with how the iPhone/iTouch uses an Accelerometer and a Gyroscope which assists in viewing content on the device whilst rotating it.
