What a great website and cool way to present a technical topic. Online education is still in its infancy and when we talk nowadays about good examples of online education, we usually think of videos and (in the best case) of websites where students can play with interactive models, solve exercises, etc. But this website demonstrates that you can still go mucher further in involving the listener as a person.

This of course requires an enormous effort in the preparation of the material.

I second this. I've just spent the summer putting together an online experiment for a student along similar lines:

I wish I'd known about the Javascript face analysis beforehand! And also how hard it would be to learn Javascript ;) And how to do that cool embedded video thing.

The immediate feedback about how I did is nice, but also may pollute the data in a way. Once I got it right, I new to retry a very similar expression for the next 1-2 tries. But then, most people might actually know how to make human expressions naturally. Personally, I appreciated this as a tool to help me learn how to human. :-)

Agreed. I found the presentation of the material more interesting and innovative than the topic itself.
