Khan Academy: Prezi in action at TED?

You should watch this TED talk by Salman Khan, a former hedge fund analyst who is now fully devoted to turning the education system upside down (see his Khan Academy). His key concept is to humanize the class room using technology: have kids watch videos at home at their own pace and use the time of the teacher in the class room to provide individual support instead of one-size-fits-all lectures.

Now to Prezi. I think Salman is using it as his presentation engine. I am still not convinced that it is a good large audience presentation tool (see an earlier discussion on whether Prezi is a PowerPoint killer). However, the tool does a good job in visualizing the enormous video library Salman has constructed, and the carefully thought-through construction of the curriculum he is proposing. What do you think?
