2010 April 7. Ken Burns Effect with CSS3 (with WebKit keyframes for animation). Gecko, Presto, and Trident effectively have no equivalents, so it will not work in those browsers. This was a proof of concept.
Javascript was used to change images with alternating animations.
CSS3 animations are a part of the W3C spec, but were still in working draft at the time of this project. Much of the CSS is the same, sans the vendor prefix. (http://w3.org/TR/css3-animations)
