I’m always interested in sharing examples of educational media. The field, such that it is, has a long way to go. But the potential of sophisticated educational media is extraordinary and will (eventually) serve as a powerful tool for learning.
The example below could be improved, certainly – for example, by increasing the time between items (in effect, slowing down the presentation of the different elements of the illustration.), and by using more accurate representations of the elements (not merely vector graphics from Prezi.) Nevertheless, it does a good job of illustrating the scale of the universe.
