This is an absolutely fascinating NPR video that shows how a virus invades your body. According to the NPR story, scientific animation outfit XVIVO produced the video:
David Bolinsky and his team at XVIVO designed this animation for a research company called Zirus (and we thank Zirus for letting us play with their pictures). Bolinsky says what you see in the video actually happens much, much faster in real life - in a fraction of a fraction of a second. So this is a very slow motion version of cellular activity.
