Animation=Information (it should be that way)
Some of you would remember this graphic by John Grimwade, published five years ago. A powerful image, with information that explains the big problem of the air traffic congestion at the USA at first sight.
With time (althought we're talking just five years ago), things change, and we have more tools for explaining same data. And these tool should been used always to improve Same code, same icons and just using animation, this graphic shows much more information,a s you can watch at this NASA video (click on image to watch the video)
A good example of animation providing information, and not just as decoration.
