This is great! Even more so, because it might be a glimpse of a 'next-gen' PDF format. PDF can include vector graphics. In the same way that SVG encompasses both static and animated images, there's no reason why similar graphics in a 'PDF-next' document shouldn't be animatable, with a fall-back to static images for printed output...
