A nice overview of "beginner" programming languages and environments framed as "how to teach Python to a 10-year-old" given by a (very well spoken) 10-year old, Jake Sethi-Reiner.
Great job!
I also find it very interesting to see coursera and free-software type ethos in general resonating with kids! Amazing to think about what the future holds for sharing knowledge like this :)
