About CSS3 Ken Burns
The 'Ken Burns effect' is a common name for a particular style of rostrum camera effect, made popular by Ken Burns for documentaries. It adds life to static photographs and is commonly used by Apple & Google for their photo apps.
This particular implementation is designed to make use of CSS3 2D transforms, and is a little crude. If I ever get around to re-doing it, I'll use the 'transition' property, as I think it'd be easier to work with than the 'animation' properties for this particular job.
I'm indebted to Tom Chislett, who inspired me with his sweet slideshow app for the iPhone and iPad, Slideways.
