I've attended last week a Code.org workshop about teaching K-5 kids computers. Unfortunately, when you look at the upcoming "Hour of code" (http://code.org/learn), PHP for kids is missing there.
Could you please create a "PHP Tutorial" version for kids, similar to Ruby's http://hackety.com/ or
Python's https://groklearning.com/ - both are mentioned on http://code.org/learn
If we want the young generations to use PHP, we need something to win their hearts and minds!
