Flip through your cards visually, in 3D "cover flow" view much like iTunes albums. Contact name and company name is displayed under the card. Touch the card to open it.

The cards list view automatically switches to the 3D view - just tilt your iPhone into landscape mode! An explicit "Show 3D view" button is also available to toggle back and forth.

You can watch the 3D card view in the 2nd half of this YouTube video (1min45 mark).
